Resin composition for molding

Abstract

The present invention provides a resin composition for molding capable of producing a molded article that has excellent heat distortion resistance, excellent mechanical properties, high impact resistance, and high transparency and has a smaller change in weight at high temperature. The present invention also provides a molded article and a joint each produced from the resin composition for molding. Provided is a resin composition for molding, including: a chlorinated polyvinyl chloride resin; a polyvinyl chloride; and a thermal stabilizer, the chlorinated polyvinyl chloride resin containing structural units (a) to (c) represented by the following formulas (a) to (c) in proportions of 5 to 90 mol % of the structural unit (a), 5 to 40 mol % of the structural unit (b), and 5 to 55 mol % of the structural unit (c) based on a total number of moles of the structural units (a), (b), and (c), the polyvinyl chloride being contained in an amount of 1 to 30 parts by mass based on 100 parts by mass of the chlorinated polyvinyl chloride resin, [Chem. 1] —CH2—CHC1-  (a) —CH2—CC12-  (b) —CHC1-CHC1-  (c).
