Abstract
A cross-linked composition produced by exposing a mixture including a telechelic polyisobutylene-containing base polymer which carries multiple terminal acrylate groups as a part thereof, a reactive diluent, and in some cases, a high-energy sensitizer, to high-energy radiation. The base polymer may also comprise a block copolymer which has polyisobutylene, and polydiene blocks as, for example, polyisoprene, and in which the polydiene blocks, advantageously partially cyclized, carry multiple acrylate groups as a part thereof. Among other things, the compositions have particular application in the formation of films useful in the electronic, biomedical, specialty adhesive, sealant, and other fields.
