بیشترCelanese 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.
بیشترPolyvinyl Acetate 3. Brief History • Poly(vinyl acetate) was discovered in Germany in 1912 by Fritz Klatte. • The monomer, vinyl acetate, was first produced on an industrial scale by addition of acetic acid to acetylene with a mercury(I) salt but it is now primarily made by palladium catalyzed oxidative addition of acetic acid to ethylene.
بیشترPVA/EVA/PVOH glue: Water and other ingredients such as preservatives are mixed with ethylene-vinyl acetate (EVA), polyvinyl acetate (PVA) or polyvinyl alcohol. These products can usually be manufactured without heat (cook) and can be made into a ready-to-use or concentrate product that is packaged in pails, drums, totes and even tankers.
بیشترThe primary use for vinyl acetate is as a monomer in the production of polyvinyl acetate and polyvinyl alcohol (IARC 1986). These products, synthesized via polymerization of vinyl acetate, accounted for 75%-80% of total U.S. consumption in 1982 (Mannsville 1982, 1988). Vinyl acetate is also polymerized with vinyl chloride to produce copolymers.
