Abstract
A new terpolymer of acrylamide with sodium acrylate and (2-methacryloyloxyethyl)trimethylammonium chloride initiated with 60Co γ-ray was prepared in inverse emulsion. Polymerization conversion was studied dilatometrically and molecular weight was determined viscometrically. The effects of dose rate, monomer concentration, emulsifier content, temperature, etc. on the polymerization rate or conversion and the molecular weight of polymer were examined. The rate of polymerization (Rp) can be represented by Rp∝D1.03[M]0.69[E]−0.02. The overall activation energy for the rate of polymerization is 12.90 kJ mol−1 (33—56°C). Based on these experimental results, aspects of the polymerization mechanisms are discussed.
