✦ Synopsis

The influence of polyvinyl pyrrolidone (PVP) on the polymerization of acrylic acid in dilute aqueous solution has been studied. The fact that the system becomes heterogeneous has been used to provide a turbidimetric method for following the polymerization. The rate of polymerization has been found to depend on the concentration of PVP, reaching a maximum at close to equimolar concentrations, based on monomer units. The kinetics of the system have been studied and have been found to exhibit characteristics of both heterogeneous polymerizations, and what might be expected of a "replica polymerization".

The complex formed as a result of the polymerization has been examined by intrinsic viscosity and electrophoresis studies, and has been found to consist apparently of PVP, polyacrylic acid (PAA) and a graft copolymer of these polymers.
