摘要

Process for the preparation of a complex Compound based on Poly (Vinyl alcohol) and a compound which forms complexes with Poly (Vinyl alcohol). At a temperature of 10 to 50 c meets an alcoholic solution of Poly (vinyl ester) that has a degree of polymerization of 400 to 10.000 with an alcoholic solution of compound Complex forming an inorganic Compound, such as Boron, obtaining a mixture of transparent Solutions. This mixture was distributed evenly in an alcoholic solution in an environment of a basic Catalyst for alcoholysis of Poly (vinyl ester), such as an alkali metal alkoxide.The alcohol Solvent is preferably used in the three Solutions, for example, a Lower aliphatic alcohol. These compounds are used as Binders and thickeners, binders in the Paper Industry, Glues and Adhesives, in aqueous solution, in the textile industry.
