Abstract
PURPOSE: To improve water absorption properties and adhesiveness of the resin composn. produced and to minimize water extraction rate, by incorporating polyacrylic acid and polyvinylpyrrolidone into a saponified product of an ethylene-vinyl acetate copolymer (EVA).
CONSTITUTION: EVA contg. 80W98mol% ethylene is saponified by a conventional method. Polyacrylic acid and polyvinylpyrrolidone in combination as water-soluble high-molecular materials are added to the saponified product. The mixt. is kneaded. The resulting compsn. is molded into a film or a mold which is then used. Not only the water absorption properties of the compsn. is improved, but also adhesiveness of the saponified product to cellulosic materials or metals is still improved.
