| Abstract: | he kinetics of emulsion copolymerization of BA and St using dodecyl dimethyl benzyl ammonium chloride as emulsifier was studied. The effect of the concentration of emulsifier, initiator, monomer and polymerization temperature on polymerization rate(Rp) were investigated in detail; The kinetic equation Rp= K M]0.72I]0.63E]0.96 and the apparent activation energy Ea=79.615kJ/mol were obtained. Some discusion for the reaction oder of reactant in copolymerization system were also given. |
