  This invention relates to substantially transparent solid solution polymer blends having improved hydrolytic stability, and flexibility which comprise (a) a linear aromatic polyester containing as monomer units the residues of a dicarboxylic acid and a bisphenol, and (b) a linear aromatic polysulfonate containing as monomer units the residues of a bisphenol and a disulfonic acid. The polyblends are useful in preparation of films and molded articles.

• Glass fiber-filled polybutylene terephthalate compositions and molded articles of diminished warpage formed therefrom

  This invention relates to a thermoplastic polymeric composition which comprises a glass fiber-filled polybutylene terephthalate and which contains a minor amount of a polymeric additive consisting of a substantially halogen-free linear bisphenol polyester consisting of a bisphenol monomer residue and a dicarboxylic acid monomer residue and having a relatively low intrinsic viscosity. Molded articles formed from the compositions exhibit substantially diminished warpage without a deleterious effect on the other properties of the glass fiber-filled polybutylene terephthalate. Preferred compositions of the invention also exhibit enhanced tensile strength compared to glass fiber-filled polybutylene terephthalate not containing the bisphenol polyester.

  本发明涉及一种热塑性聚合物组合物，该组合物由玻璃纤维填充聚对苯二甲酸丁二醇酯组成，并含有少量聚合物添加剂，该添加剂由基本上不含卤素的线性双酚聚酯组成，该线性双酚聚酯由双酚单体残留物和二羧酸单体残留物组成，具有相对较低的固有粘度。用这种组合物制成的模塑制品可大大减少翘曲，而不会对玻璃纤维填充聚对苯二甲酸丁二醇酯的其他性能产生有害影响。与不含双酚聚酯的玻璃纤维填充聚对苯二甲酸丁二醇酯相比，本发明的优选组合物还具有更高的拉伸强度。
