THE RELATIONSHIP BETWEEN THE MOLECULAR WEIGHT AND THE MONOMER CONCENTRATION IN INVERSE MICROEMULSION POLYMERIZATION FOR SOLUBLE MONOMERS WITH DIFFERENT IONIC GROUPS

摘要

The inverse microemulsion polymerization is a very new subject in recent years. Many reports concentrated on the polymerization kinetics, and few publishes on the molecular weights. On the other hand, most researches were developed under the different conditions such as different initiator system, emulsifier, monomer concentrations, so the results are uncomparable. In this paper, we select three kinds of monomer or monomer pairs acrylamide(AM) acrylamide/sodium acrylate (AM/SA )and acrylamide/(2-methacryloyloxyethyl)trimethyl ammonium chloride(AM/DM.MC) with different ionic groups as polymerized monomers and completed inverse microemulsion polymerization under the same conditions and determined the relationships between the molecular weights (expressed by intrinsic viscosity)and the monomer concentrations.
