MONOVINYLARENE CONJUGATED DIENE BLOCK COPOLYMER COMPOSITIONS FOR SHRINKABLE FILMS

摘要

The present invention relates generally to monovinylarene-conjugated diene block copolymers adapted for shrinkable film applications. In one embodiment, a block copolymer is provided wherein an oriented 2 mil film of the block copolymer oriented at 100°C or less exhibits less than 10% shrinkage at 70°C, and at least 70% shrinkage at 100°C.
