Acrylamide polymers are one of very important water soluble polymer. Due to their excellent advantages, these polymers have been widely utilized as wastewater treatment flocculants in many areas, such as, petroleum industry, paper making, coal preparation, textile industry, domestic sewage and so on. In this paper, cationic polyacrylamide microspheres are successfully synthesized by dispersion polymerization in ethanol-water mixture. This special precipitation polymerization firstly requires that monomers, ...
