Polymerization Of Vinyl Acetate Monomer

Addition polymerization needs initiator to generate free radicals lead to the propagation of the polymer chain during radical. 19 gois et al. Vinyl acetate monomers vac were polar and reactive however theydifficult to be polymerizedwithlesspolar and more reactive monomers.

Acetate monomer previous to its use in the polymerization process.

Polymerization of vinyl acetate monomer.

However a higher degree of control has been reported by us ear lier 3 we have reported that the radical polymeriza. Have reported the polymerization of pvac in bulk using s benzyl o ethyl dithiocarbonate as the madix agent with molecular weights of up to 30 050 g mol 1 although the monomer conversions were incomplete ranging from 68 to 83 conversion. The controlled radical polymerization of vinyl acetate monomer is reported to be difﬁcult 2 the facile termi nation and chain transfer of vinyl acetate makes con trol of vinyl acetate polymerization difﬁcult. Although vinyl acetate was by far the most studied monomer of the range many vinyl esters have been considered in order to tune various polymer properties in particular solubility in supercritical carbon dioxide scco2.

It can be polymerized to give polyvinyl acetate pva. Therefore the study of vinyl acetate bulk polymerization is of great interest from a process safety point of view even if it is not a commercial wide spread process. With other monomers it can be used to prepare various copolymers such as ethylene vinyl acetate eva vinyl acetate acrylic acid va aa polyvinyl chloride acetate pvca and polyvinylpyrrolidone vp va copolymer used in hair gels. 73 polymerization of vinylacetateandacrylicacid monomersusing.
