Abstract
The present invention relates to styrene-based thermoplastic resin compositions in which 1-10 weight part of a low-gloss additive selected from a group consisting of polyolefin copolymer(C) containing glycidyl methacrylate functional groups, styrene polymer(D) harboring two or more carboxyl functional groups per molecule, and a mixture of them, was added to 100 weight part of basic resin composed of 30-70 weight part of graft copolymer(A) containing rubber modified styrene and 30-70 weight part of copolymer(B) harboring styrene. The thermoplastic resin composition of the present invention has excellent impact strength and satisfactorily low gloss.
Claims8
A thermoplastic resin composition in which 1-10 weight part of a low-gloss additive of polyolefin copolymer (C) containing glycidyl methacrylate functional groups and styrene polymer (D) harboring two or more carboxyl functional groups per molecule, is added to 100 weight part of basic resin composed of 30-70 weight part of graft copolymer (A) containing rubber modified styrene and 30-70 weight part of copolymer (B) harboring styrene,
- wherein the olefin forming main chain for the polyolefin copolymer (C) is propylene or ethylene and weight average molecular weight of polyolefin copolymer (C) is 20,000-50,000.
