The present invention provides a molding resin composition capable of producing a molded body having excellent thermal stability, flexibility, and high strength without using heavy metals such as lead and tin, and a molded body using the molding resin composition.nn n n The present invention is a resin composition for molding, which contains a chlorinated vinyl chloride resin and a heat stabilizer, and the chlorinated vinyl chloride resin has a constituent unit (a) to be represented by the following formulas (a) to (c). (c) and the ratio of the unit (a) to 17.5 mole% or less and the ratio of the unit (b) to 46.0 relative to the total mole number of the units (a), (b), and (c) above Molar% or more, the ratio of the constituent unit (c) is 37.0 Molar% or less, the chlorine content in the above chlorinated vinyl chloride resin is 63% by mass to 72% by mass, and the heat stabilizer contains an alkyl carboxylic acid The calcium and zinc compounds and the molding resin composition have a heating loss rate of less than 2% by mass at 230 ° C.nn n n -CCl 2- (a)n n n -CHCl- (b)nn n n -CH 2- (C) |
