摘要：
本发明的目的在于，提供一种热稳定性优异的氯化氯乙烯系树脂组合物及其成形体。本发明提供一种成形用树脂组合物，其含有氯化氯乙烯系树脂、热稳定剂、以及多元醇和/或多元醇的偏酯，其中，上述氯化氯乙烯系树脂中的氯含量为65重量％以上且低于72重量％，上述氯化氯乙烯系树脂中，相对于结构单元(a)-CCl2-、结构单元(b)-CHCl-、及结构单元(c)-CH2-的合计摩尔数，结构单元(a)的比例为17.5摩尔％以下，结构单元(b)的比例为46.0摩尔％以上，结构单元(c)的比例为37.0摩尔％以下，上述热稳定剂含有由通式Ca1-xMgx(OH)2表示的化合物(式中，x满足由不等式0＜x＜1表示的关系)及由通式Ca1-yMgyO表示的化合物(式中，y满足由不等式0＜y＜1表示的关系)中的至少一种。
摘要（英）：

The purpose of the present invention is to provide a chlorinated vinyl chloride-based resin composition having excellent thermal stability and a molded article thereof. This resin composition for molding includes a chlorinated vinyl chloride-based resin, a heat stabilizer, and a polyhydric alcohol and/or a partial ester of a polyhydric alcohol. The chlorine content in the chlorinated vinyl chloride-based resin is at least 65 wt% and less than 72 wt%. The chlorinated vinyl chloride-based resin has a ratio of a constituent unit (a) (-CCl2-) of no more than 17.5 mol%, the ratio of a constituent unit (b) (-CHCl-) of at least 46.0 mol%, and the ratio of a constituent unit (c) (-CH2-) of no more than 37.0 mol%, relative to the total number of moles in constituent units (a), (b), and (c). The heat stabilizer includes at least either a compound indicated by general formula Ca1-xMgx(OH)2 (in the formula, x fulfils the relationship indicated by the unequal expression 0
