| Abstract: | Based on a lot of experiments,a stable and transparent microemulsion system has been obtained by mixing acrylamide(AM),2-(methacryloyloxy)-ethyltrimethylammonium chloride(MADQUAT) and sodium-2-acrylamido-2-methylpropanesulfonate(NaAMPS) as monomers.Span20 and Tween80 were emulsifiers and hexamethylene was the oil phase in this article.The pseudoternary phase diagram of microemulsion was drawn and divided into W/O,bicontinuous(BC) and O/W districts basis of the conduct of system.The effects of the emulsifier concentration on intrinsic viscosity of the copolymer,the particle size of the microlatexes,and the time of polymerization on the particle size of microlatex and the conversion were studied.Then the polymerizations in W/O and BC microemulsion were compared. |
