Title
(JA) 樹脂組成物およびパイプ継手
Abstract
(JA)

本発明は、透明性に優れる新たな塩化ビニル系樹脂組成物、ならびにこの樹脂組成物から形成される成形体、特にはパイプ継手を提供することをその目的とする。本発明の樹脂組成物は、塩素含有率が５５〜７５質量％である塩化ビニル系樹脂（Ａ）１００質量部に対して、ＤＳＣにおけるガラス転移温度（Ｔｇ）が０℃以下であるゴム系衝撃吸収材（Ｂ）３〜１５質量部、下記要件（ｉ）〜（ｉｖ）を満たす滑剤（Ｃ）０．１〜１０質量部を含む。
（ｉ）２００℃における溶融粘度が５〜５，０００ｍＰ・ｓである
（ｉｉ）軟化点が６０〜１８０℃の範囲にある
（ｉｉｉ）示差走査熱量計（ＤＳＣ）で測定したガラス転移温度（Ｔｇ）が０〜１００℃の範囲にある
（ｉｖ）分子中に、スチレン、α−メチルスチレン、インデン、ビニルトルエン、およびイソプロペニルトルエンからなる群から選ばれる少なくとも１種に由来する構造単位を５０〜１００質量％含有する
