PROBLEM TO BE SOLVED: To provide an injection molding composition that allows easy and simple injection molding at lower temperature than in the conventional art, and improves the strength of an injection-molded article.SOLUTION: There is provided an injection molding composition at least containing HPMCAS with a degree of molar substitution of a hydroxypropoxy group being 0.40 or more. There is also provided a method for producing an injection-molded article including at least the step of injecting the injection molding composition into a mold at 50-250°C.SELECTED DRAWING: NoneCOPYRIGHT: (C)2019,JPO&INPIT【課題】従来よりも低い温度で簡便に射出成型が可能であり、射出成型物の強度を改善した射出成型用組成物を提供する。【解決手段】ヒドロキシプロポキシ基のモル置換度が0.40以上のHPMCASを少なくとも含む射出成型用組成物が提供される。また、この射出成型用組成物を、50~250℃でモールドに射出する工程を少なくとも含む射出成型物の製造方法が提供される。【選択図】なし
