Effects of Leaving Group Ability and Microstructure on the Reactivity of Halogenated Poly(isobutylene-co-isoprene)
McNeish, Joanne (2011-10-03)Halogenation of poly(isobutylene-co-isoprene) (IIR) increases its reactivity towards sulphur and other nucleophiles. Currently brominated (BIIR) and chlorinated (CIIR) derivatives are commercially available; however, an ... -
Imidazolium Ionomer Derivatives of Isobutylene-Rich Elastomers: Thermosets, Emulsions, Filler Composites and Clay Nanocomposites
Kleczek, Monika (2013-12-11)Ionomers are valued for their exceptional physical properties, antimicrobial activity and superior adhesion to high surface energy solids and polymer blend components. Carboxylate, or sulfonate derivatives, of ethylene-rich ... -
Imidazolium Ionomer Derivatives of Poly(isobutylene-co-isoprene)
Porter, Anthony Martin John (2011-02-03)The allylic bromide functionality in brominated poly(isoprene-co-isobutylene) rubber (BIIR) reacted readily to nucleophilic substitution by imidazole-derivatives. When reacted with the rubber, alkylimidazoles formed a ... -
Latent Amine Cures of Brominated Poly(isobutylene-co-isoprene)
Faba, Michael A. J. (2010-02-02)The allylic bromide functionality within brominated poly(isobutylene-co-isoprene), or BIIR, alkylates primary amines repeatedly to generate thermoset products at reaction rates that are too fast to support commercial rubber ... -
Nucleophilic Catalysis of Brominated Butyl Rubber Substitution Reactions
Malmberg, Sean Magnus (2009-10-06)The allylic bromide functionality within brominated poly(isobutylene-co-isoprene), or BIIR, is amenable to substitution by a wide range of nucleophiles. The objective of this work was to gain insight into the dynamics of ... -
Peroxide Curable Butyl Rubber Derivatives
Siva Shanmugam, Karthik Vikram (2012-07-06)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 ... -
Reactive Ionomers: N-vinylimidazolium Bromide Derivatives of Poly(isobutylene-co-isoprene) and Poly(isobutylene-co-para-methylstyrene)
Ozvald, Adam Michael (2012-04-02)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 ...
