Abstract: Polymer compositions comprising styrene butadiene block-copolymers (SBC) can be used for shrink-wrap films, a stiff star-shaped SBC block copolymer A having two short branches of a single copolymer block (B/S)Ai and two long branches of the structure St-[(B/S)A]n-(B/S)Ai or [(B/S)A]n-(B/S)Ai are used in said polymer composition, and the production of shrink-wrap films and of multilayer films is described.

Abstract: Polymer compositions comprising stiff and tough star shaped styrene butadiene block-copolymers A1 and A2 can be used for making shrink films. Block copolymer A2 preferably has the structure with hard blocks Se and Si, hard random copolymer blocks (B/S)Ae, soft random copolymer blocks (B/S)B coupled by a coupling agent X.
