Abstract
The present invention aims to provide a resin composition for molding that makes it possible to achieve excellent continuous productivity and to produce a molded article having high surface smoothness, capable of reducing defective molding, less likely to crack during use, and also having excellent shock resistance. The present invention also aims to provide a molded article including the resin composition for molding. Provided is a resin composition for molding, containing: a chlorinated polyvinyl chloride resin; and a melt additive, the resin composition containing three components including a Acomponent, a Bcomponent, and a Ccomponent, and having a percentage of the Ccomponent [Ccomponent/(Acomponent+Bcomponent+Ccomponent)] of 30% or less, the three components being identified by measuring the resin composition by a solid echo method using pulse NMR at 100° C. to give a free induction decay curve ofH spin-spin relaxation, and subjecting the free induction decay curve to waveform separation into three curves derived from the Acomponent, the Bcomponent, and the Ccomponent in order of shorter relaxation time using the least square method.
