Block copolymer resin composition

Abstract

Abstract PURPOSE: The titled resin composition with good stretching characteristics capable of giving a product with excellent properties after stretching, which is prepd. by blending two kinds of special styrene-butadiene block copolymers. CONSTITUTION: 100pts.wt. styrene-butadiene block copolymer of styrene content 60W90wt%, butadiene content 40W10pts.wt. and degree of styrene blocking 90W 100%, and 10W100pts.wt styrene-butadiene random block copolymer of styrene content 30W80wt%, butadiene content 70W20wt% and degree of styrene blocking 0W75% in which at least 25% of the bonded styrene is contained as a random copolymer or tapered copolymer with butadiene, are dry-blended by use of a kneader, or may be blended and directly extruded by use of an extruder.
