摘要： In an inverse emulsion polymerization system for producing water-soluble polymers from a monomer system comprising an N-vinyl lactam and/or a vinyl-containing sulfonic acid or salt thereof utilizing a surfactant system having (1) a surfactant with a bulky lipophilic portion and a hydrophilic portion and (2) a generally straight-chain nonionic surfactant having a lipophilic hydrocarbon group and an OH-terminated hydrophilic group, i.e. an alcohol. Such a system having both the right HLB and the right chemical cobination results in a stable emulsion for the polymerization of these particular water-soluble monomers.
