Emulsion Polymerization Of Vinyl Acetate Butyl Acrylate

The order of the polymerization reaction with respect to behm was calculated using the two different monomers and found to be 1 3 and 1 for vinyl acetate and butyl acrylate respectively.

Emulsion polymerization of vinyl acetate butyl acrylate.

Acrylate were achieved by using bis 2 ethylhexyl maleate behm. Acrylic elastomer possesses characteristics of heat and oil resistance with the ability to withstand temperatures of 170 180.

It is used primarily for producing oil seals and packaging related to automobiles.

Vinyl acetate va butyl acrylate ba emulsion copolymers with various comonomer ratios have been prepared by different emulsion polymerization pathways conventional batch semi continuous. Potassium persulfate kps was used as initiator. In this manuscript the emulsion polymerization of vinyl acetate and butyl acrylate in presence of bis 2 ethylhexyl maleate behm was studied. The emulsion polymerization kinetics of vinyl acetate and butyl acrylate in presence of behm was studied.

George street toronto ontario m5s 3h6 canada. Polymerization emulsion polymerizations of butyl acrylate were carried out at 70 c. The concentrations of ammonium persulfate and dowfax 2a1 were changed and used as shown in results and discussion. Emulsion copolymerization of vinyl acetate and butyl acrylate in the presence of fluorescent dyes jung kwon oh department of chemistry university of toronto 80 st.

The emulsifier free emulsion polymerization of vinyl acetate vac and butyl acrylate ba in the presence of 2 acrylamido 2 methylpropane sulfonic acid amps was carried out by a semi continuous process. Amps was a reactive surfactant in the aqueous emulsion due to its amphiphilic structure and the unsaturated double bonds. In all cases the recipe comprised 145 g of water and 95 6 g of butyl acrylate.
