Professor

Our process development/modeling efforts are only possible with knowledge of the underlying polymerization mechanisms and accurate values of kinetic rate coefficients. Thus, many of our projects include the study of polymerization kinetics using the PLP/MMD technique, in which pulsed-laser polymerization (PLP) is combined with analysis of the resulting polymer molar mass distribution (MMD) to directly estimate kp, the chain growth rate coefficient for radical polymerization.

Dr. Hutchinson is a pioneer in the development and application of PLP, leading a program to utilize the new technique to measure kp values for many monomers of industrial interest while at DuPont (1991-2000). He is currently co-chair of the IUPAC (Polymer Division) subcommittee on Polymerization Mechanisms and Kinetics, and has on-going collaborations regarding the analysis and interpretation of PLP/MMD experimentation with Dr. Anatoly Nikitin. The laser setup at Queen's is the only one of its kind in North America. Our laser for PLP/MMD studies was purchased in 2013 thanks to an NSERC "Research Tools and Instrumentation" grant, and sees continuous use supporting a range of recent and ongoing projects, including the ongoing investigation of radical copolymerization kinetics in aqueous vs organic solution and in alcohol/water mixtures (Ibrahim Refai and Maryam Agboluaje, sponsored by NSERC and BASF)

Findings from the PLP/MMD technique are often combined with NMR measurements of copolymer composition or branching levels to develop new mechanistic insights regarding hydrogen-bonding effects on polymerization kinetics, copolymerization penultimate effects, and acrylate side-reactions. In addition, we continue to study new monomer systems to support development of new materials.

In addition, the equipment has been used for a number of undergraduate thesis projects supporting research efforts in the Hutchinson group.

Water-soluble polymers are used for a wide range of applications in the cosmetics, pharmaceutical, water treatment, and coatings industries. Funded by BASF (Germany), we work closely with the research groups of Professor Michael Buback (University of Göttingen, Germany) and Professor Igor Lacík (Polymer Institute of the Slovak Academy of Sciences, Bratislava, Slovakia), who are applying pulsed-laser techniques to the study of polymerization kinetics in water. They have shown that the propagation kinetics of these monomers vary with concentration and conversion when polymerized in the aqueous phase, a behavior not seen for polymerization in organic solvents. In addition, the formation and consumption of midchain radicals affects aqueous phase (co)polymerization rates of acrylic acid and acrylamide.

Based on this new understanding, the Hutchinson group has developed computer models for the batch and semibatch aqueous-phase homo and copolymerization of a range of systems, verified against experiments conducted in the laboratory. The studies not only supply information useful for industrial process and product development of these environmentally-friendly polymerization systems, they also provide unique insight to the effect of solvent on radical polymerization kinetics. PhD student Maryam Agboluaje is currently investigating acrylate-acrylamide copolymerization kinetics in alcohol/water mixtures experimentally using an in-situ NMR technique, with the results providing the understanding needed to develop a detailed mechanistic model of the system. The effort is supported by a PLP/MMD study conducted by Ibrahim Refai, and a semi-batch radical polymerization investigation by Gagandeep Kaur.

Recently graduated PhD student Ikenna Ezenwajiaku developed models to represent the complex copolymerization kinetics of cationic monomers with acrylic acid, following the previous efforts of Calista Preusser who studied the copolymerization of acrylic acid and acrylamide as a function of monomer concentration and system pH. Key to the studies is experimental determination of comonomer composition drift using an in-situ NMR technique.

The manufacture of synthetic polymers produced via radical polymerization is energy intensive and often utilizes solvents to control system viscosity or for heat removal. This strong impetus to reduce the environmental footprint has led to a shift in the process technology used to produce the polymer component of most automotive clearcoats. Currently, low molar mass polymer chains are produced with low solvent content; these chains form a polymer network on the surface to be coated via reaction of the functional groups with an added cross-linking agent. Sufficient functional monomer (e.g., hydroxyethyl acrylate, glycidyl methacrylate) must be included in the resin recipe to ensure that close to 100% of the chains participate in the cross-linking reactions.

Secondary reactions have a marked effect on rate and polymer structure under the polymerization conditions used industrially. The Hutchinson group has studied the mechanisms and constructed models to represent how methacrylate depropagation, acrylate branching and scission, and penultimate chain-growth copolymerization kinetics control reaction rate and polymer molecular weight during high-temperature acrylate/methacrylate, styrene/methacrylate, and styrene/acrylate copolymerization. The improved understanding is captured in models used to improve manufacturing practices and reduce the effort required to develop new coatings resins. Recent efforts have extended the studies to include hydroxyfunctional monomers, the development of kinetic Monte-Carlo techniques to model the distribution of functionality among the low-MW polymer chains, and the optimization of semi-batch operating strategies to improve both product uniformity and process efficiency. This research has been funded continuously by Axalta Coating Systems (formerly DuPont Performance Coatings) since 2001, with matching funds obtained at times through NSERC.

  • Maximizing TDB functionality in acrylate copolymers through semibatch production (Dr. Nina Heidarzadeh and Elizabeth Bygott, sponsored by Saint-Gobain Research North America)
  • Solution copolymerization kinetics and semibatch production of polymers with hydroxyl-functional monomers (Loretta Idowu, sponsored by Axalta Coating Systems)

An ongoing program explores the industrial application controlled radical polymerization (CRP) to produce polymers with narrow molar mass distribution and controlled structure. In particular, the group has studied the application of Cu-catalyzed systems known collectively as Atom Transfer Radical Polymerization (ATRP). The technique has great promise, but several factors must be overcome (residual Cu catalyst concentration; expensive reagents; lower polymerization rate) before it is industrially viable. The group has constructed tubular and well-mixed reactor systems for continuous production of polymer with controlled chain lengths at ppm levels of Cu catalyst at reaction rates that approach those of conventional free radical polymerization. Current process development focuses on Cu(0)-mediated production of poly(acrylate) macroinitiators in a tubular reactor, followed by chain-extension to produce block copolymers in a semi-batch process.

Current and recent projects in this area include:

  • Cu(0)-Mediated Routes to Acrylate Macromonomers (Morgan Cooze, sponsored by Nipsea Technologies)
  • The use of CRP techniques to synthesize dispersants for non-aqueous dispersion polymerization (Mingmin Zhang, sponsored by Axalta Coating Systems)
  • Industrial process development: low-copper ATRP systems and new alkoxyamines for high temperature (Kevin Payne, sponsored by BASF)

Every year finds one or two 4th year CHEE or ENCH students conducting research in the Hutchinson lab. In addition, there is the occasional opportunity to gain summer work experience under the NSERC USRA program. The projects are designed to allow the student to work independently on a topic that is related to an ongoing group research project, under the supervision of a graduate student in the lab. Contact Dr. Hutchinson if you are interested! Some of the students -- most recently Elizabeth Bygott, Morgan Cooze, Kyle Lister, Sharmaine Luk, and Otlaatla Monyatsi -- have stayed with the group as graduate students, and occasionally the undergraduate research leads to a research publication to add to your CV.
