| description | Disclosed is a foaming vinyl chloride resin composition having excellent foaming properties and provides 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 contains a powder with a (meth)acrylic polymer with a weight average molecular weight of 2,000,000 to 7,000,000. The (meth)acrylic polymer comprises 1 to 20wt.% of a (meth)acrylic polymer (A) with a weight average molecular weight of 10,000 to 300,000 and 80 to 99wt.% of a (meth)acrylic polymer (B) with a weight average molecular weight of 2,000,000 to 7,000,000. |
