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.
