- Structure/Property Relationships in Ionomeric Materials
Our research program is focused on the chemical modification of polymers for use in high-value engineering applications. Using knowledge of the relationships between polymer structure and end-use performance, the structural inadequacies of polyolefins and elastomers are defined and remedied through chemical modification. Our aim is to develop commercially viable chemistry for the production of advanced polymeric materials.
Research projects range from studies of the structure-property relationships of new materials to detailed analyses of reaction kinetics and selectivity. While the focus remains on the development of advanced polymers, model compounds are studied extensively to determine the underlying chemistry of modification processes. Most projects therefore involve organic synthesis, reactive polymer processing, spectroscopic characterization and polymer property assessment.
Two areas of current interest are:
Peroxide-Initiated Graft Modification of Polyolefins
Materials such as polyethylene and polypropylene are functionalized by radical-initiated grafting of unsaturated monomers (e.g. maleic anhydride, vinylsilanes) to yield high-value products for the automotive, packaging, and composites industries.
Research projects in this area range from "blue-sky" methods of improving reaction selectivity to product engineering exercises focused on the preparation of polyolefin nanocomposites for advanced automotive applications.
Synthesis of Elastomer Derivatives
Novel elastomers are being developed by nucleophilic substitution and cycloaddition reactions of commercial materials such as halogenated butyl rubber and polybutadiene. These projects are concerned not only with the yield, rate and selectivity of polymer modifications, but also with the physical and chemical properties of the product. Extensive use is made of model compounds that represent the reactive functionality of a polymer to create new chemistry, while studies of polymeric systems provide the data needed for product development.
