ABSTRACT:
A polymer blend comprises a high nitrile copolymer and a compatible thermoplastic polymer or copolymer containing polar groups, formed from monomers selected from the group consisting of alkylacrylamides, aliphatic and cyclic methacrylates, unsaturated carboxylic acid anhydrides, vinyl pyrrolidones, heterocyclic ring compounds containing two hetero atoms, lactones and phosphorus-containing monomers that form highly crystalline polymers. Such blends can be used to form films and membranes having improved thermal, mechanical and optical properties.
