Copolymerization of acrylamide and sodium acrylate in microemulsions

Conference paper
Part of the Progress in Colloid & Polymer Science book series (PROGCOLLOID, volume 73)

Abstract

“New Trends in Colliod Science” contains the proceedings of the foundation meeting of the European Colloid and Interface Society (ECIS), October 1–3, 1986. Representatives from the major European groups working in this field contributed to the conference. The volume contains an up-to-date account of present developments in Colloid Science. The contributions cover a wide scope of subjects, and provide encouragement that structures and transport processes in dense colloidal systems can be understood on basic principles. The main subjects are include:
  • phase diagrams of new surfactant systems

  • microemulsions and their applications

  • vesicles and bilayers

  • transport properties of colloidal systems.

Abstract

We have investigated the thermal copolymerization of acrylamide and sodium acrylate in nonionic microemulsions. The formation of microemulsions is strongly related to the acrylate content in the comonomer feed due to a salting out effect of the ethoxylated surfactant. After polymerization, clear and stable inverse latices are formed which contain high solid contents (up to 23%) dispersed in the oil-continuous medium. The dimensions of the particles are rather low (450 Å<d<700 Å) with a narrow distribution. They decrease with increasing emulsifier or sodium acrylate concentrations.
