Abstract

PURPOSE: Title composition having excellent strength, durability and water-swellability, which is useful as a material for packings, joints, etc., comprising a polyvinyl chloride resin and a saponified product of a starch/acrylonitrile copolymer.
CONSTITUTION: To (A) 100pts.wt. of a polyvinyl chloride resin are added (B) 25W350pts.wt. of a plasticizer such as dioctyl phthalate or dioctyl adipate and (C) 2W300pts.wt., pref., 50W200pts.wt. of a saponified starch/acrylonitrile copolymer prepared by grafting an acrylonitrile compound onto a starch such as wheat starch or rice starch, and saponifying the resulting graft copolymer in the presence of an alkali. When the composition is used as a material for packings, the packings do not shrink, but increase in volume with the lapse of time by absorption of water.
