ABSTRACT:
Blends of 5 to 97.5% of a segmented thermoplastic copolyester such as polybutylene terephthalate containing polybutane glycol segments with 95 to 20% of a blend of an ethylene copolymer and 5 to 75% either polyvinyl chloride or polyvinylidene chloride. The polyethylene copolymer is an elastomeric blend of polyvinyl chloride or polyvinylidene chloride with a copolymer of ethylene and esters of ethylenically unsaturated acids, vinyl esters, vinyl alkyl ethers, vinyl chloride, vinylidene chloride acrylonitrile, methacrylonitrile, norbornene, alpha-olefins of 3-12 carbon atoms and optionally ethylenically unsaturated carboxylic acids, carbon monoxide and sulfur dioxide. The blends are processable temperatures lower than either component they are prepared from.
