A process for preparing an aqueous solution of polyvinyl alcohol sizing based.

摘要

Preparation method of Aqueous Solutions of polyvinyl alcohol sizing based.Is the preparation of an aqueous solution containing 45.5 to 99.9% of a polymer of vinyl alcohol, as alcohol polvinilico or Copolymer of vinyl alcohol - methyl methacrylate; add to this dissolution of 0.1 to 3% of an Adduct Ionic Liquid, Low ethylene oxide A branched alcohol, or mixtures of these alcohols; and heating the mixture, while stirring;At a temperature of 77jc until complete dissolution. These compositions have applications for sizing and desizing, thermobonding aqueous Textile factories.
