GRAFT COPOLYMER, METHOD FOR PRODUCING SAME AND RESIN COMPOSITION CONTAINING SUCH GRAFT COPOLYMER

摘要

Disclosed are a novel graft copolymer and a resin composition having an excellent balance between flame resistance and impact resistance. Specifically disclosed is a polyorganosiloxane graft copolymer containing a polyorganosiloxane component (A), a polymer component (C) having at least a unit derived from a nitrogen atom-containing polyfunctional monomer (B) having two or more radically polymerizable groups in a molecule, and another polymer component (E) which is derived from an ethylenically unsaturated monomer (D) and has a glass transition temperature of not less than 40°C. Also specifically disclosed is a resin composition containing such a graft copolymer.
