Weight Fraction Of A Poly Vinyl Acetate

Poly vinyl acetate containing a small amount of n benzyl 4 vinylpyridinium chloride pvac co vpc and that containing 16 mol of methyl acrylate and a small amount of the pyridinium group pvac co ma co vpc showed significant degradation when placed in an aeration tank of sewage works.

Weight fraction of a poly vinyl acetate.

Since vinyl alcohol is highly unstable with respect to acetaldehyde the preparation of vinyl acetate is more complex than the synthesis of other acetate esters. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. 3 the monomer vinyl acetate was first produced on an industrial scale by the addition of acetic acid to acetylene with a mercury i salt 4 but it is now primarily made by palladium catalyzed oxidative addition of acetic acid to ethylene. Poly vinyl acetate was discovered in germany in 1912 by fritz klatte.

1 and table 3 correlation results of the sl eos are shown in fig. Polymers formed by a straightforward linking together of monomer units with no loss or gain of material are called addition polymers or chain growth polymers a listing of some important addition polymers and their monomer precursors is presented in the following table. Poly vinyl chloride co vinyl acetate co vinyl alcohol 1 product result match criteria. 1 the solubilities increased linearly with increasing pressure and decreased with increasing temperature.

Solubilities of ethylene in molten eva were measured at temperatures of 393 15 k 443 15 k and 473 15 k and at pressures up to 10 mpa. Control polymers possessed of no. Vinyl acetate is the acetate ester of vinyl alcohol. Many polymeric materials having chain like structures similar to polyethylene are known.
