Vinyl Acetate is a clear, colorless liquid with a faint ether-like odor. It is only sparingly soluble in water but readily soluble in many organic solvents such as ethyl acetate and ethanol. It is a highly flammable liquid. In the presence of water, it forms an azeotrope, which boils at 66 °C under atmospheric pressure, that contains 92.7 % Vinyl Acetate. Vinyl Acetate is stabilized with 3 – 5 ppm of Hydroquinone to prevent uncontrolled polymerization during handling and storage. Vinyl Acetate with higher amount of hydroquinone is available upon request.
Applications: reactions with other esters. This chemical property makes it a very versatile monomer; it readily forms homo-polymers and hetero-polymers with a wide range of other monomers such as ethylene, acrylates, vinyl chloride, fumarate esters, and maleate esters among others. It polymerizes under the influence of various activators such as light, heat or peroxides. The vinyl acetate monomer can be polymerized in the mass as well as in the form of a solution, suspension (pearl form) or emulsion. The latter form is widely used for the production of synthetic resin dispersions, general and pressure sensitive adhesives and in the paint, textile and paper coating industries. Solution and suspension polymers are used in coatings and adhesives. Suspension polymers, in addition, are used in plastics. Secondary products from vinyl acetate polymers are the polyvinyl alcohols, from which the polyvinyl acetals are produced. Fields of applications for polyvinyl acetate, polyvinyl acetate secondary products and their co- and terpolymers are:
Polyvinyl acetate is suitable as a binder and raw material for the production of paints, adhesives, paper coatings, finishing agents for textiles and non-wovens, and resin-bound plasters.
Polyvinyl alcohol is employed as a thickening agent and protective colloid and is also used in the form of a solution, for instance in the production of adhesives, paper, textiles and cosmetics.
Polyvinyl acetals, e.g. polyvinyl butyral, are used for instance in the manufacture of paints, primers, electrical resins, printing inks and films for laminated glass.
Acrylonitrile / vinyl acetate copolymers are employed in the production of acrylic fibers.
Methacrylic acid / vinyl acetate copolymers are suitable for the production of paints for interior and exterior use. Vinyl acetate/ethylene/vinylchloride (VAEVC) terpolymers are used in the form of dispersions for the production of abrasion-resistant interior paints, exterior wall paints, resin-bound plasters and cement additives.
Vinyl acetate/ethylene (VAE) and vinyl acetate/vinyl versatate copolymers with a predominance of Vinyl acetate are employed as dispersions e.g. for the production of adhesive films for textiles (nonwovens) and crosslinking agents.
Ethylene/Vinyl acetate (EVA) copolymers with a large proportion of ethylene are suitable for the modification of low-density polyethylene for engineering plastics (e.g. automotive industry) and for the production of shrink film and other films.
Ethylene / vinyl alcohol (EVOH) copolymers are used for the production of food packaging materials because of their excellent oxygen barrier properties.
