The present invention provides a resin composition for molding, including a chlorinated polyvinyl chloride and a thermal stabilizer, the chlorinated polyvinyl chloride having structural units (a) to (c) represented by formulae (a) to (c) shown below:&#x2014;CCl&#x2014;&#x2003;&#x2003;(a),&#x2014;CHCl&#x2014;&#x2003;&#x2003;(b),&#x2014;CH&#x2014;&#x2003;&#x2003;(c),

Resin composition for molding use

The present invention aims to provide a chlorinated vinyl chloride-based resin composition with excellent thermal stability and a molded body thereof. The present invention relates to a resin composition for molding, including a chlorinated vinyl chloride-based resin, a thermal stabilizer, and a polyalcohol and/or a partial ester of a polyalcohol. The chlorinated vinyl chloride-based resin has a chlorine content of 65% by weight or more and less than 72% by weight. The chlorinated vinyl chloride-based resin has, based on the total number of moles of a structural unit (a) &#x2014;CCl&#x2014;, a structural unit (b) &#x2014;CHCl&#x2014;, and a structural unit (c) &#x2014;CH&#x2014;, a proportion of the structural unit (a) of 17.5 mol % or less, a proportion of the structural unit (b) of 46.0 mol % or more, and a proportion of the structural unit (c) of 37.0 mol % or less. The thermal stabilizer contains at least one of a compound represented by the formula CaMg(OH)where x satisfies the inequality 0&#x3c;x&#x3c;1 and a compound represented by the formula CaMgO where y satisfies the inequality 0&#x3c;y&#x3c;1.
