Title (EN) POLYMER COMPOSITION
(FR) COMPOSITION DE POLYMÈRE
(JA) ポリマー組成物
Abstract:
(EN) This polymer composition contains a polymer component that is a polyoxylate having a diol-derived diol constituent unit and an oxalic acid-derived acid constituent unit. The polymer composition is characterized by containing a terminal carboxyl group sealant as a molding stabilizer in addition to the polyoxylate, and by having a 5% weight loss temperature of 300°C or less as measured by TG-DTA.
(FR) L'invention concerne une composition de polymère qui contient, en tant que composant polymère, un polyoxalate possédant une unité structurale diol dérivée d'un diol et une unité structurale acide dérivée d'un acide oxalique. Cette composition de polymère est caractéristique en ce qu'elle contient, avec ledit polyoxalate, un agent de blocage de groupe carboxyle terminal, en tant qu'agent de stabilisation de moulage, et en ce qu'elle présente une température de perte de poids de 5 % selon TG-ATD inférieure ou égale à 300°C.
(JA) ポリマー成分として、ジオール由来のジオール構成単位とシュウ酸由来の酸構成単位を有するポリオキサレートを含むポリマー組成物において、前記ポリオキサレートと共に、成形安定剤として、末端カルボキシル基封止剤を含んでおり、TG-DTAによる5%重量減少温度が300℃以下であることを特徴とする。
