<p>Molded articles are disclosed that comprise polymer blends prepared by blending polyesters prepared from terephthalic acid, 40 to 5 mole percent 2,2,4,4-tetramethy-1,3-cyclobutanediol, and 60 to 95 mole percent 1,4- cyclohexanedimethanol, with bisphenol A polycarbonate. The composition of the blend includes up to about 95 weight percent bisphenol A polycarbonate. These blends have a combination of clarity, toughness and heat resistance making the materials particularly useful in engineering molding plastics and packaging.</p> |
