Abstract
Isobutylene rubber particles comprising a finely divided isobutylene polymer, and isobutylene-based graft copolymer particles comprising the isobutylene rubber particles and a vinyl monomer graft-polymerized onto the particles, which are useful as an impact modifier having excellent weatherability and thermal stability for thermoplastic resins and provide a thermoplastic resin composition having an improved impact resistance.
