摘要： The present invention relates to a novel copolymerized composition characterized in that it comprises (A) 100 parts by weight of a copolymerized polyester containing (a) an aromatic dicarboxylic acid unit composed mainly of a terephthalic acid unit, (b) a glycol unit composed mainly of an ethylene glycol unit, (c) a polytetramethylene glycol unit, (d) a polyethylene glycol unit and (e) an aliphatic dicarboxylic acid unit having 9 or more carbon atoms, (B) 5 to 150 parts by weight of a reinforcing substance and (C) 1 to 10 parts by weight of a metal salt of an ionic copolymer.The copolymerized polyester compositions of the present invention retain excellent heat resistance and rigidity that the glass fiber-reinforced polyethylene terephthalate compositions possess originally and are considerably improved in terms of low-temperature moldability, toughness, alkali resistance and like other factors.

摘要翻译： 本发明涉及一种新型共聚组合物，其特征在于它包含（A）100重量份的共聚聚酯，其含有（a）主要由对苯二甲酸单元组成的芳族二羧酸单元，（b）主要组成的二醇单元 的乙二醇单元，（c）聚四亚甲基二醇单元，（d）聚乙二醇单元和（e）具有9个或更多个碳原子的脂族二羧酸单元，（B）5至150重量份的增强物质 和（C）1至10重量份的离子共聚物的金属盐。 本发明的共聚聚酯组合物保持了玻璃纤维增​​强聚对苯二甲酸乙二醇酯组合物原本具有优异的耐热性和刚性，并且在低温成型性，韧性，耐碱性等方面具有显着改善。
