Polyazoester(PAE) was obtained by the reaction of AIBN and PEG400. The kinetics of thermal decomposition by DSC gave Ea = 146.6 KJ/mol and A = 5.2×1017s-1.The PAE was used to indicate radical polymerization of methacrylic acid limiting the decomposition of initiator to 37%. This azo group-containing polymethacrylic acid(prepoly-mer) was neutralized by NaOH
thus
a macroinitiator-emulsifier was obtained. It had critical micelle concentration of 0.05 to 0
15 and surface tension of 58 to 68 mN/m.The results show that the kinetics of emulsion polymerization usingthis macroinitiator-emulsifier possesses similiar characteristics of he norral emulsion polmerization.
