By fine tuning the ethylene pressure and the vinyl acetate content a broad range of copolymers containing from 0 to 85 mol of vac unit was achieved.

When a vinyl monomer like propylene comes to the active metal center it can be coordinated to ti atom by overlapping their orbitals. By this route using mercury ii catalysts vinyl acetate was first prepared by fritz klatte in 1912. In the production of ethylene vinyl acetate copolymers in a free radical catalyst initiated high pressure process explosive decomposition is prevented by contacting the reactor effluent downstream.

The copolymerization by itp itcop of ethylene with vinyl acetate vac to form poly ethylene co vinyl acetate eva copolymer was also successful. The effects of temperature pressure added co solvent vinyl acetate feed rate and emulsifier type and concentration on the rate of polymerization cumulative copolymer composition molecular. Therefore vinyl acetate runaway polymerization incidents are very serious and they occur with a high frequency. Eva generally contains 1 50 of the va comonomer along the carbon chain backbone.

Vinyl acetate was once prepared by hydroesterification. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. This method involves the gas phase addition of acetic acid to acetylene in the presence of metal catalysts. A prior extensive experimental phase identified those variables that are most important for ethylene vinyl acetate emulsion copolymer production.

The polymerization of vinyl acetate is probably the second most frequent cause of runaway reaction accidents in the chemical industry after the phenol formaldehyde runaway reaction. Eva copolymers are commercially used predominantly in the areas of coating laminating and in the film industries. Coordination copolymerization of vinyl acetate vac with ethylene leading to linear copolymers that possess in chain ch 2 ch oac units has been accomplished using novel palladium complexes bearing alkylphosphine sulfonate ligands.
