PURPOSE:To obtain the title resin composition improved in processability without lowering its heat distortion temperature, by adding specified amounts of an organotin carboxylate and zeolite A to a resin composition comprising a post-chlorinated vinyl resin and a toughening agent. CONSTITUTION:0.3-2.0pts.wt. organotin carboxylate of formula I (wherein R is a 1-12C alkyl and R<1> is a 11-21C alkyl or alkenyl) and 0.1-2.0pts.wt. zeolite A of formula II (wherein M is a monovalent cation or a polyvalent cation in an amount equivalent thereto and is Na, K, NH4, Ca, Mg, Sr or Zn) are added to a resin composition obtained by mixing 100pts.wt. post-chlorinated vinyl chloride resin of a chlorine content of 63-70% (which may contain optionally at most 20wt.% PVC), obtained by suspending PVC alone or together with a chlorinated hydrocarbon solvent in water and chlorinating it. |
