Polyvinyl alcohol is used as an emulsion polymerization, as protective colloid, to make polyvinyl acetate dispersions. This is the largest market application in China. Some other uses of polyvinyl alcohol include:

.Paper adhesive with boric acid in spiral tube winding and solid board production

.Thickener, modifier, in polyvinyl acetate glues 

.Textile sizing agent

.Paper coatings ,release liner 


PVA is unique among polymers (chemical compounds made up of large, multiple-unit molecules) in that it is not built up in polymerization reactions from single-unit precursor molecules known as monomers. Instead, PVA is made by dissolving another polymer, polyvinyl acetate (PVAc), in an alcohol such as methanol and treating it with an alkaline catalyst such as sodium hydroxide. The resulting hydrolysis, or “alcoholysis,” reaction removes the acetate groups from the PVAc molecules without disrupting their long-chain structure.
