摘要
Inverse microemulsion copolymerizations of acrylamide(AM) with acrylimide ethyltrimethylammonium chloride(AETMAC) have been carried out in the systems of non ionic emulsifier SPAN 80 and anionic emulsifier sodium di(2 ethyl) hexyl phosphate(DOP), respectively, and the effects of the emulsifiers on the copolymerization rate and reactivity ratio have been investigated. The copolymerization rate was found higher in DOP system and the reactivity ratio of AETMAC was lower in SPAN 80 system than in DOP system and aqueous solution. The results are explained in terms of the difference in tightness of emulsifier layers.
