A method for preparing a graft copolymer having a polyolefin main chain and a polyorganosiloxane pendant group.

摘要

A method for preparing a graft copolymer having a polyolefin backbone and a polyorganosiloxane pendant group can be catalyzed by a Lewis acid catalyst, a Piers-Rubentzjan catalyst, or a hydrosilylation reaction catalyst. The graft copolymers prepared by this method are useful as thermoplastic elastomers or as compatibilizers in compositions containing both polyolefins and polyorganosiloxanes. [Selection diagram] None
