PURPOSE:To obtain a styrene polymer composition excellent in transparency and impact resistance. CONSTITUTION:This composition comprises 30-70wt.% nonrubber-modified styrene polymer, 20-60wt.% block copolymer comprising a conjugated diolefin and a vinyl-substituted aromatic compound and having a content of the vinyl- substituted aromatic compound of 65-90wt.%, 5 to below 10wt.% block copolymer comprising a conjugated diolefin and a vinyl-substituted aromatic compound and having a content of the vinyl-substituted aromatic compound of 15-50wt.% and 0.5 to below 2wt.% high-impact rubber-modified styrene polymer having a mean rubber particle of 0.2-4.0mum and a content of the elastomer of 3-15wt.%. |
