Abstract

PURPOSE: A linear block copolymer containing conjugated dienes and another branched block copolymer are incorporated to a polystyrene to produce title composition with high toughness, clarity, impact strength and tensile properties.
CONSTITUTION: (A) 55-82 wt.% of polystyrene is blended with (B) 15-35 % of a linear block copolymer containing 40% or more content of conjugated diene and beig given as formula I,II (A is block of aromatic vinyl polymer; B is other block of conjugated diene; n is positive and integral number) and (C) 3-15% of a branched block copolymer containing 40% or less content of conjugated diene and being given as formula + [Y is polyfunctional agent for forming branched chains such as polyepoxide; X is number of functions, integral number of over 2].
