Description
即ち、本発明は
(A)ポリブチレンテレフタレート樹脂100重量部に対して、
(B)扁平な断面形状を有するガラス繊維40〜140重量部、
(C)グリセリン及び/又はその脱水縮合物と炭素数12以上の脂肪酸とからなり、本文記載の方法により測定した水酸基価が200以上のグリセリン脂肪酸エステル0.05〜5重量部
を配合してなるポリブチレンテレフタレート樹脂組成物、およびそれからなる薄肉成形品である。
(A)ポリブチレンテレフタレート樹脂
ポリブチレンテレフタレート樹脂とは、テレフタル酸(テレフタル酸またはそのエステル形成誘導体)と、炭素数4のアルキレングリコール(1,4 −ブタンジオールまたはそのエステル形成誘導体)を少なくとも重合成分とする熱可塑性樹脂である。本発明の(A)ポリブチレンテレフタレート樹脂とは、ポリブチレンテレフタレートホモポリマーに限らず、イソフタル酸変性ポリブチレンテレフタレート、イソフタル酸変性ポリエステルを含有するポリブチレンテレフタレートも含まれ、そり変形の面からは、イソフタル酸変性ポリブチレンテレフタレート、イソフタル酸変性ポリエステルを含有するポリブチレンテレフタレートが好ましく使用できる。
各樹脂組成物を表1、2に示す混合比率でドライブレンドし、30mmφのスクリューを有する2軸押出機((株)日本製鋼製)を用いて、シリンダー設定温度250℃で溶融混練したのちペレット化し、試験片を作成し、各評価を行った。結果を表1、2に示す。
