Abstract
A styrenic resin composition with little foul odor is provided. The styrenic resin composition contains: (1) 99.995-95.0 wt % of a styrenic resin which is made from 5-100 wt % of rubbery graft copolymer (A) and 95-0 wt % of styrenic copolymer (B), wherein the rubbery graft copolymer (A) is prepared by graft polymerization of 50 to 90 wt % of vinyl aromatic monomers, 10 to 50 wt % of vinyl cyanide monomers and 0-40 wt % of copolymerizable monomers in the presence of rubbery polymer; and (2) 0.005-5.0 wt % of a sesquiterpene compound (C).
