GLASS FIBER-FILLED POLYBUTYLENE TEREPHTHALATE COMPOSITIONS AND MOLDED ARTICLES OF DIMINISHED WARPAGE FORMED THEREFROM |
摘要 |
This invention relates to a thermoplastic polymeric composition which comprises a glass fiber-filled polybutylene terephthalate and which contains as an improvement a warp-inhibiting amount of a polymeric additive consisting of a linear aromatic substantially halogen-free polyester consisting of a bisphenol monomer residue and a dicarboxylic acid monomer residue and having a relatively low intrinsic viscosity. The compositions exhibit substantially diminished warpage on molding 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 comparable pure glass fiber-filled polybutylene terephthalate. |
