Abstract:
An object of the present invention is to provide a foaming vinyl chloride resin composition having excellent foaming properties and providing a foam molded product with an excellent appearance by enhancing the melt strength of the vinyl chloride resin composition. A processability improver for foam molding according to the present invention includes a (meth)acrylic polymer powder with a weight average molecular weight of 2,000,000 to 7,000,000, wherein the (meth)acrylic polymer powder includes 1 to 20% by weight of a (meth)acrylic polymer (A) with a weight average molecular weight of 10,000 to 300,000, and 80 to 99% by weight of a (meth)acrylic polymer (B) with a weight average molecular weight of 2,000,000 to 7,000,000.
