Aqueous solution polymerization of acrylamide at low conversions: 1. Kinetics and transfer studies

Abstract

The aqueous polymerization of acrylamide, initiated by 4,4'-azobis-4-cyanovaleric acid, has been studied in the presence of propionamide, and oligoacrylamide, at 30-90°C. Molecular weights were determined viscometrically and transfer constants to propionamide, oligoacrylamide and monomer were evaluated. Exponents expressing the dependency of initial polymerization rate on monomer and initiator concentrations at 50°C were 1.16±0.01 and 0.52±0.03, respectively. © 1988.
