SILICONE-CONTAINING BLOCK COPOLYMER

摘要

A silicone−containing block copolymer obtained by bonding a polymer (a) to a silicone polymer (b); and a thermoplastic resin composition containing the block copolymer. The polymer (a) is obtained by radical−polymerizing a radical−polymerizable monomer (a0) in the presence of a specific compound having a thiocarbonylthio group. The silicone−containing block copolymer and thermoplastic resin composition are excellent in flame retardancy, moldability, and impact resistance.
