Abstract
Polymer blends comprising polyesters made from terephthalic acid; 2,2,4,4-tetramethyl-1,3-cyclobutanediol; and 1,4-cyclohexanedimethanol, and copolymers made from acrylonitrile, butadiene, and styrene (ABS) monomers. These blends have a combination of toughness, heat resistance, high modulus, and good flowability—making them particularly useful in films, fibers, engineering molding plastics, and packaging.
