NO.108-05-4
Vinyl acetate Monomer, also known as VAM, is an organic compound, chemical formula C4H6O2, is an important organic chemical raw material.
Application
(1). Used for organic synthesis, mainly used for synthetic vinylon, also used for binder and coating industry. Used in resin fiber synthesis, also used as oil point drop thickening agent intermediate and binder.
(2). Vinyl acetate is the main raw material of vinylon. Through polymerization of vinyl acetate itself, or copolymerization with the monomer, polyvinyl alcohol, ethylene acetate - ethylene copolymer (EVA), ethylene acetate - vinyl chloride copolymer (EVC), ethylene acetate - acrylonitrile fiber, ethylene acetate - acrylate copolymer, they all have important industrial uses. It is widely used as binder, architectural coating, textile sizing agent and finishing agent, paper strengthening agent, and used in the manufacture of safety glass. Bromoacetaldehyde diethyl alcohol can be prepared by the reaction of vinyl acetate with ethanol and bromine. This is an intermediate of the drug methimazole.
(3). It is a very widely used organic and polymeric adhesive synthetic monomer. Used for making polyvinyl acetate emulsion (white latex); Copolymerization of EVA resin and VAE emulsion with ethylene; Copolymerization with vinyl chloride to produce chlorinated vinegar emulsion and chlorinated vinegar resin; Solvent polymerization manufacturing 4115 senior building adhesive; Copolymerization with butyl acrylate to produce propylene acetate emulsion; And butyl acrylate copolymerization in the solvent to prepare the building sealant; Used as a hard monomer for making acrylate emulsions; And styrene butadiene rubber grafting to make PVC wood film adhesive. It is also the main raw material for the production of polyvinyl alcohol and vinylon. Through solution or emulsion polymerization to manufacture adhesive, emulsifier, fabric finishing agent, coating, paper coating, cement additives, food anti-corrosion coating, food packaging film, gum base material, cosmetic additives, etc.
(4). This product is the monomer of polyvinyl acetate and the raw material of polyvinyl alcohol resin, but also can form copolymer with other monomers, can produce water treatment agents, rubber, coatings, adhesives and other fine chemicals.
