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 Sand S, hard random copolymer blocks (B/S), soft random copolymer blocks (B/S)coupled by a coupling agent X.

Intrinsically non-blocking shrink sleeve material

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)and two long branches of the structure S-[(B/S)]-(B/S)or [(B/S)]-(B/S)are used in said polymer composition, and the production of shrink-wrap films and of multilayer films is described.

Polymer compositions for shrink-wrap films

A mixture which comprises from 5 to 50% by weight of a block copolymer A, which comprises one or more copolymer blocks (B/S)each composed of from 65 to 95% by weight of vinylaromatic monomers and from 35 to 5% by weight of dienes and of a glass transition temperature Tgin the range from 40&#xb0; to 90&#xb0; C.; from 95 to 50% by weight of a block copolymer B, which comprises at least one hard block S composed of vinylaromatic monomers and comprises one or more copolymer blocks (B/S)each composed of from 20 to 60% by weight of vinylaromatic monomers and from 80 to 40% by weight of dienes and of a glass transition temperature Tgin the range from &#x2212;70&#xb0; to 0&#xb0; C.; from 0 to 45% by weight of polystyrene or of a block copolymer C other than A and B; and from 0 to 6% by weight of a plasticizer; and its use for production of shrink films.
