title: Concurrent cationic vinyl-addition and ring-opening copolymerization using B(C6F5)3 as a catalyst: copolymerization of vinyl ethers and isobutylene oxide via crossover propagation reactions.
abstract: Alkyl vinyl ethers and isobutylene oxide were concurrently copolymerized through cationic vinyl addition and ring opening using B(C6F5)3 as a catalyst. NMR analyses and acid hydrolysis of the products demonstrated that the copolymerization successfully proceeded through crossover reactions between vinyl and cyclic monomers to yield multiblock-like copolymers. Appropriate catalyst and monomer combinations with suitable reactivities were key for copolymerization.
