PURPOSE:To obtain the title composition excellent in mattedness, surface appearance and heat resistance by mixing a specified graft copolymer with a specified compound and a specified polyglutarimide resin in a specified ratio. CONSTITUTION:This composition is prepared by mixing 1-99 pts.wt. graft copolymer prepared by graft-polymerizing 95-20 pts.wt. at least one vinyl monomer selected from among an aromatic vinyl monomer, a vinyl cyanide monomer and an alkyl unsaturated carboxylate and a mixture thereof (e.g. a mixture of styrene and acrylonitrile) in the presence of 5-80 pts.wt. rubbery polymer (e.g. polybutadiene) with 1-60 pts.wt. polyglutarimide resin (e.g. a resin obtained from polymethyl methacrylate and NH3) and 0.01-10 pts.wt., based on 100 pts.wt. total of the former two, compound of the formula (wherein R1 is alkyl, 1-26 C alkenyl or hydroxyalkyl; R2 and R3 are each H, R1 or hydroxyalkenyl; and Y is N or CON) (e.g. N,N-dihydroxyethylstearylamine). |
