An aromatic polyester obtained by copolycondensation of isophtalic acid and terepthalic acid or the derivatives thereof, bis(hydroxyphenyl)sulfone, and 2,2-bis(4'-hydroxyphenyl)propane. This aromatic polyester has a good moldability and provides colorless, transparent moldings by a molding process such as compression moldin, extrusion molding or injection molding. The resulting moldings possess good mechanical and electrical properties, and improved heat resistance.
一种芳香族聚酯,由异酞酸和对苯二甲酸或其衍生物、双(羟基苯基)砜和 2,2-双(4'-羟基苯基)丙烷共聚而成。 这种芳香族聚酯具有良好的成型性,可通过压缩成型、挤压成型或注塑成型等成型工艺制成无色透明的成型品。 所制成的成型品具有良好的机械和电气性能,耐热性能也有所提高。
