Abstract
Herein disclosed are a block copolymer having an isobutylene-based polymer block and a vinylic aromatic hydrocarbon-based polymer block and containing a styrenic unit having a halogenated saturated aliphatic hydrocarbon group on the benzene ring at 0.01 to 2 mol % on a basis of the total structural units and being capable of markedly improving the performance of a synthetic resin when the block copolymer is blended with the synthetic resin; a process for producing the block copolymer; and a resin composition position containing the block copolymer.
