POLYVINYL ALCOHOL-CLAD SHAPED ARTICLE OF VINYL CHLORIDE RESIN

摘要

The invention provides a novel method for the preparation of a composite shaped article of a vinyl chloride-based resin clad with a coating layer of polyvinyl alcohol without the use of any adhesive agent. The method comprises subjecting the surface of the shaped article to exposure to an atmosphere of low temperature atmosphere, coating the thus plasma-treated surface of the shaped article with an aqueous solution of a polyvinyl alcohol and drying. The coating layer of the polyvinyl alcohol thus formed is so firmly bonded to the surface of the vinyl chloride-based resin shaped article that various advantageous properties are imparted to the shaped article.
