polyvinyl alcohol (PVA), a colourless, water-soluble synthetic resin employed principally in the treating of textiles and paper. 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 ...

Celanese is a global leader in polyvinyl acetate homopolymer emulsions, often called PVAc or occasionally PVA homopolymers. Polyvinyl acetate is synthesized by the emulsion polymerization of vinyl acetate monomer (VAM). PVAc emulsions are best known for their use in wood glues or school glues due to their strong adhesion properties.
