Abstract: Controlled radical initiators, reaction mixtures containing the controlled radical initiators and various ethylenically unsaturated monomers, and polymeric materials formed from the reaction mixtures are provided. The controlled radical initiators are bis-dithiocarbamate or bis-dithiocarbonate compounds with a single carbon atom between the two dithiocarbamate or dithiocarbonate groups. Polymeric materials such as homopolymers, random copolymers, and block copolymers can be prepared using the controlled radical initiators.

Abstract: Adhesive composition are described comprising the reaction product of at least one halogenated copolymer of isobutylene wherein halogen atoms of the copolymer are replaced by a polyamine having a melting point greater than 25° C., thereby crosslinking the copolymer. The isobutylene copolymer comprises halogenated repeat units derived from isoprene, butadiene, para-alkyl styrene, or a combination thereof. The adhesive composition comprises a copolymer of isobutylene repeat units and second repeat units selected from alkene repeat units, para-methyl styrene repeat units, or a combination thereof wherein at least a portion of the second repeat units are directly bonded to one another with a polyamine crosslinker having a melting point greater than 25° C. Also described are adhesive articles, such as tapes, comprising such adhesives.
