摘要： The method of producing plasticized polyvinyl alcohol by mixing polyvinyl alcohol in the presence of an organic plasticizer and water in a quantity which is insufficient to dissolve the polyvinyl alcohol under normal conditions, includes the steps of:i) pre-plasticizing the polyvinyl alcohol at a maximum temperature no higher than its softening point so as to produce a pre-plasticized polyvinyl alcohol having a melting point below the softening point of the polyvinyl alcohol used, andii) further processing the pre-plasticized polyvinyl alcohol thus produced at a temperature above its melting point, under shear-stress conditions and for a period of time to produce a substantially homogeneous melt.
