Abstract
A molding composition on the basis of polyvinyl alcohol substantially consists of a partially solvolyzed graft copolymer of a vinyl ester and a polyethylene glycol or of a mixture of such graft copolymer with a partially solvolyzed polyvinyl ester as well as of water and optionally a polyhydric alkanol. The composition is obtained by mixing the granular polymers used in each case with the other components. It is water-soluble, flowable and thermoplastically workable and is suitable for the preparation of any shaped articles, especially sheets.
