Composite rubber particles and graft copolymer particles of composite rubber

Abstract

The present invention provides the composite rubber particles and graft copolymer particles of composite rubber which can be used as the impact modifier being excellent in weather resistance, thermal stability, and particularly impact resistance without substantially lowering transparency of each resin. The composite rubber particles have intertwined molecular chains of the isobutylene polymer and the vinyl polymer so that the both polymers cannot be separated substantially from each other and the graft copolymer particles of composite rubber are prepared by graft-polymerizing at least one vinyl polymer to the above composite rubber particles.
