KINETICS OF EMULSIFIER-FREE EMULSION BUTYL ACRYLATE COPOLYMERIZATION WITH WATER-SOLUBLE MONOMERS

The effect of temperature, monomer composition, and initiator concentr ation on the kinetics of emulsifier-free emulsion butyl acrylate copol ymerization with acrylonitrile and methacrylic acid, dispersion proper ties, mechanisms of formation and stabilization of latex particles are studied. It is found that qualitatively the effect of the above-indic ated factors on the reactions of chain growth and termination in water is the same as in polymerization in the presence of emulsifier. But t he role of the aforesaid elementary reactions in the polymerization pr ocess and the conditions of particle stabilization alter, which gives rise to different kinetic effects.
