PURPOSE: To obtain a vinyl chloride resin molding material capable of giving molded articles having improved creep characteristics, with uniform composition and good continuous processability, by kneading a non-rigid vinyl chloride resin composition with an acrylic ester under heating.
CONSTITUTION: (A) 100 parts by wt. of a non-rigid vinyl chloride resin composition is kneaded with (B) 2W30 parts by wt. of an acrylic ester under heating if necessary in the presence of 0.02W0.30 part by wt. of a polymerization initiator, e.g. dicumyl peroxide, to give a vinyl chloride resin composition. For example, components (A) and (B) are kneaded in a Banbury mixer at 120W200°C for 1W 10min. Liquid methyl acrylate having a low molecular weight is preferred as (B).
