Functional Imidazolium Ionomer Derivatives of Isobutylene-Rich Elastomers

摘要

Macromolecules containing small amounts of ionic functionality, collectively known as ionomers, are valued for their exceptional physical properties, antimicrobial activity, and superiour adhesion to high surface energy solids and polymer blend components. This report describes cationic ionomers prepared by halide displacement from brominated poly(isobutylene-co-isoprene) (BUR) or brominated poly(isobutylene-co-methylstyrene (BIMS), using imidazoles that can provide thermoset ionomers directly, or bear reactive functionality for further chemical modification.
