Molecular weight ethylene vinyl acetate.

The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. As the va content increases crystallinity decreases until at 50 the eva is.

Emblem in packaging technology 2012. At 50 c the solubility of vinyl acetate in water is 0 1 wt more than at 20 c but the solubility of water in vinyl acetate doubles to about 2 wt.

The va comonomer interferes with chain packing reducing crystallinity and thus lowering t m and improving transparency when compared with ldpe. Chemsrc provides vinyl acetate cas 108 05 4 msds density melting point boiling point structure formula molecular weight etc. World eva capacity is projected to increase at an average annual rate of about 5 per year through 2023 while consumption is expected to increase at 4 per year over the same period. Poly ethylene co vinyl acetate vinyl acetate 25 wt.

At 20 c a saturated solution of vinyl acetate in water contains 2 0 2 4 wt vinyl acetate whereas a saturated solution of water in vinyl acetate contains 0 9 1 0 wt water. 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.
