Polyester Resin Composition, Process for Producing the Same and Molding Thereof
摘要：
To provide a polyester resin composition whereby formation of a cyclic trimer, etc. during melt molding is suppressed, and little soiling or the like is observed during the molding, and a method for its production. A method for producing a polyester resin composition (C), which comprises melt-kneading a polyester resin (A) which satisfies the following formulae (1), (2) and (3) and a polyester resin (B) which satisfies the following formula (4). The polyester resin composition (C) obtained by the method, and a molded product such as a film made from such a composition. P1≧10  (1) 0.1≦Ge1≦1.5  (2) 0.001≦Ge1/P1≦0.15  (3) 0≦P2/Ti1≦80  (4) provided that in the formulae (1), (2) and (3), P1 is the content (mol) of phosphorus atoms and Ge1 is the content (mol) of germanium atoms, per ton of the polyester resin (A), and in the formula (4), P2 is the content (mol) of phosphorus atoms and Ti1 is the content (mol) of titanium atoms, per ton of the polyester resin (B).
摘要（中）：

提供一种聚酯树脂组合物，其在熔融成型期间形成环状三聚体等，并且在成型期间观察到少量污渍等及其制造方法。 一种聚酯树脂组合物（C）的制造方法，其特征在于，将满足下述式（1），（2）和（3）的聚酯树脂（A）和满足以下的聚酯树脂（B）熔融捏合 公式（4）。 通过该方法获得的聚酯树脂组合物（C）和由这种组合物制成的膜等成型体。 <？in-line-formula description =“In-line Formulas”end =“lead”？> P1> = 10（1）<？in-line-formula description =“In-line Formulas”end =“tail”？ > <？in-line-formula description =“In-line Formulas”end =“lead”？> 0.1 <= Ge1 <= 1.5（2）<？in-line-formula description =“In-line Formulas”end = “tail”？> <？in-line-formula description =“In-line Formulas”end =“lead”？> 0.001 <= Ge1 / P1 <= 0.15（3）<？in-line-formula description =“In 线“公式”end =“tail”？> <？in-line-formula description =“In-line Formulas”end =“lead”？> 0 <= P2 / Ti1 <= 80（4）<？ 式（1），（2）和（3）中，P1是磷原子的含量（mol），Ge1是含量（mol） mol）的锗原子，每吨聚酯树脂（A），在式（4）中，P2是磷原子的含量（mol），Ti 1是钛原子的含量（mol），每吨 聚酯树脂（B）。
