DEFINITION
Poly(vinyl acetate) is a thermoplastic polymer obtained by polymerisation of vinyl acetate using a suitable starter, without solvent or with water or 2-propanol. The vast majority of the acetate moieties are attached to non-neighbouring carbon atoms of the chain. The index n is about 100 - 17 000. The relative molecular mass lies between 10 000 and 1500 000. The viscosity is 4 to 250 mPas. The ester value, which characterises the degree of hydrolysis, is 615 to 675.

Polyvinyl Acetate FCC Food Grade Specifications
CAS 9003-20-7
DESCRIPTION
Polyvinyl Acetate occurs as a clear, water white to pale yellow, solid resin. It is prepared by the polymerization of vinyl acetate. After completion of polymerization, the resin is freed of traces of residual catalyst (usually a peroxide), monomer, and/or solvent by vacuum drying, steam sparging, washing, or any combination of these treatments. The resin is soluble in acetone, but it is insoluble in water.
REQUIREMENTS
Identification: The infrared absorption spectrum of a melted sample on a potassium bromide plate exhibits relative maxima at the same wavelengths as those of a typical spectrum as shown in the section on Infrared Spectra, using the same test conditions as specified therein.
Free Acetic Acid: Not more than 0.05%.
Lead: Not more than 3 mg/kg.
Loss on Drying: Not more than 1.0%.
Molecular Weight: Not less than 2000.
The Uses of PVA Polyvinyl Acetate:
Polyvinyl acetate serves as the film-forming ingredient in water-based (latex) paints; it also is used in adhesives. PVA adhesives are used in packaging applications such as shipping boxes and bags, food containers, envelopes, tapes, and as binders for paper, plastics, and foils. In addition to making homopolymers, vinyl acetate is combined with other monomers such as ethylene and acrylates to produce a variety of copolymers. Polyvinyl acetate commonly known as wood glue, PVA glue, white glue, carpenter's glue, school glue, or Elmer's glue. PVA is largely used in glass fiber-reinforced plastics to improve the stress and antishrink properties. It is also used in automobile headlights. Polyvinyl acetate PVA applications include transparent tape, paint, and various adhesives. In food processing it has the E-number E1520.
