Title: Inverse Emulsion Polymerization of Acrylamide and 2-Acrylamido-2Methyl Propane Sulfonic Acid
Abstract: In this paper,inverse emulsion polymerization of acrylamide and 2-acrylamido-2-methyl propane sulfonic acid,using Span-80 as emulsifier,white oil as dispersion phase,and(NH_4)_2S_2O_8-Na_2SO_3 as initiator was investigated.Effects of several important factors on the molecular weight of copolymers,such as the amount of initiator,emulsifier,the ratio of oil to water and the concentration of monomers were investigated.When the amount of initiator was 0.2‰ based on the monomers,the amount of emulsifier was 6.7% based on the oil phase,and the ratio of oil to water was 1.5,molecular weight of copolymer was highest and closed to 1×10~7.When the concentration of monomer was lower than 40%,the polymerization process was easy to control.
