STYRENIC THERMOPLASTIC RESIN COMPOSITIONS WITH GOOD MECHANICAL PROPERTIES AND LOW GLOSS

摘要

A thermoplastic resin composition is provided to improve mechanical properties such as impact strength, tensile strength, thermal deformation temperature and to reduce gloss. A thermoplastic resin composition comprises 20-40 wt% of a graft copolymer obtained by grafting an aromatic vinyl compound and a vinyl cyano compound to a conjugated diene-based rubbery polymer having an average particle size of 0.1-0.5 mm; 10-20 wt% of a graft copolymer obtained by grafting an aromatic vinyl compound and a vinyl cyano compound to a conjugated diene-based rubbery polymer having an average particle size of 2.0-10.0 mm; 40-70 wt% of a copolymer of an aromatic vinyl compound and a vinyl cyano compound; and 1-10 wt% of a low gloss additive.
