Reactive Ionomers: N-vinylimidazolium Bromide Derivatives of Poly(isobutylene-co-isoprene) and Poly(isobutylene-co-para-methylstyrene)
Ionomers bearing reactive ion-pair functionality are a novel class of materials that have been prepared. The N-alkylation of N-vinylimidazole by poly(isobutylene-co-isoprene) produced the reactive ionomer product in good ...
Peroxide-Curable Macromonomer Derivatives of Isobutylene-Rich Elastomers
Macromonomers bearing oligomerizable C=C functionality have been prepared by the nucleophilic displacement of allylic bromide functionality on brominated poly(isobutylene-co-isoprene) (BIIR). Whereas commercial grades of ...
Peroxide Curable Butyl Rubber Derivatives
Isobutylene-rich elastomers bearing functional groups that engage N-arylmaleimides in C-H bond addition and/or alternating copolymerization are described. While inactive to cross-linking when treated at high temperature ...
Additive Effects on Melt-State Modification of Commodity Polyolefins
In this work, melt-state peroxide mediated crosslinking of butyl rubber (IIR) and linear low density polyethylene (LLDPE) was used to determine additive effects, as well as the effect of higher isoprene content on the ...
