POLYBUTYLENE TEREPHTHALATE RESIN
(FR)
RÉSINE À BASE DE POLY(TÉRÉPHTALATE DE BUTYLÈNE)
(JA)
ポリブチレンテレフタレート樹脂
Abstract:
(EN)
The present invention is a polybutylene terephthalate resin which contains, as polymerization catalyst components, an aluminum compound and a phosphorus compound and has an intrinsic viscosity of 0.5-1.3 dL/g, and which generates 50 ppm or less of tetrahydrofuran and 10 ppm or less of 1, 4-butanediol when heated at 265°C for 10 minutes in an inert gas atmosphere. This polybutylene terephthalate resin is able to reduce the amounts of tetrahydrofuran and 1, 4-butanediol to be generated during molding, while having excellent thermal stability, color tone, hydrolysis resistance and transparency.
(FR)
La présente invention concerne une résine de poly(téréphtalate de butylène) qui contient, en tant que constituants catalytiques de polymérisation, un composé d'aluminium et un composé de phosphore et qui présente une viscosité intrinsèque de 0,5 à 1,3 dl/g et qui génère 50 ppm ou moins de tétrahydrofuranne et 10 ppm ou moins de 1,4-butanediol lorsqu'elle est chauffée à 265°C pendant 10 minutes dans une atmosphère de gaz inerte. Cette résine de poly(téréphtalate de butylène) peut réduire les quantités de tétrahydrofuranne et de 1,4-butanediol générées pendant le moulage, tout en présentant une excellente stabilité thermique, un excellent ton de couleur, une excellente résistance à l'hydrolyse et une excellente transparence.
(JA)
本発明は、重合触媒成分としてアルミニウム化合物及びリン化合物を含有するポリブチレンテレフタレート樹脂であって、固有粘度が0.5~1.3dL/gであり、該ポリブチレンテレフタレート樹脂を265℃、10分、不活性ガス雰囲気下で加熱した際に発生するテトラヒドロフラン、1,4-ブタンジオールがそれぞれ50ppm以下、10ppm以下であるポリブチレンテレフタレート樹脂である。該ポリブチレンテレフタレート樹脂は、成形時のテトラヒドロフラン、1,4-ブタンジオール発生量を低減でき、また熱安定性、色調、耐加水分解性、透明性に優れている。
