The factors which influence polymeric kinetics of acrylate emulsion modified by vinyl alkoxy silane through seed emulsion polymerization were investigated

and the nucleation mechanism of emulsion polymerization was analyzed. The experimental results showed that reaction temperature

initiator concentration

emulsifier concentration and vinyl alkoxy silane amount had great influence on the kinetics of emulsion polymerization.At higher temperature

higher initiator concentration

higher emulsifier concentration and less amount of vinyl alkoxy silane monomer

the conversion rate of emulsion polymerization was higher.Besides

the pH value of the system between six and eight was favorable to emulsion polymerization kinetics.In the seed emulsion polymerization

RP∝［E］0.72，RP∝［I］0.56，Ea=143.92 kJ8226;mol-1. At the beginning of the shell reaction

nucleation of emulsion polymerization occurred in monomer droplet，while during core reaction

the nucleation mechanism was “micellar nucleation”.
