Multi-component graft copolymer and thermoplastic resin composition thereof
 A muti-component graft copolymer comprises 50 to 80 wt. parts of an elastic component produced by an emulsion polymerization of 100 to 70 wt. % of a C.sub.2-12 alkyl acrylate and 0 to 30 wt. % of a comonomer having a single vinyl or vinylidene group and 50 to 20 wt. parts of a graft polymerized component produced by a graftpolymerization of 5 to 90 wt. % of a vinyl monomer having glycidyl group and 95 to 10 wt. % of a lower alkyl methacrylate, a lower alkyl acrylate, styrene, .alpha.-methyl styrene, methacrylonitrile, or acrylonitrile on the elastic component. A polymethyl methacrylate or polyvinyl chloride is blended to the multi-component graft copolymer.
