Abstract
PURPOSE: The polymerization of acryamide using an azo compound catalyst is effected in the presence of a specific sulfinic acid, whereby the low temperature polymerization is made easy and high molecular weight polymers with high solubility and storage stability for long periods of time are obtained.
CONSTITUTION: As the polymerization accelerator, is used a sulfinic acid of the formula (R is phenyl, Y-C6H5 where Y is Cl, Br, I; X is H, alkali metal) as p- chlorobenzenesulfonic acid or its alkali metal salt. Acrylamide (a), about 100W 2000ppm, based on the monomer solution, of (b) an azo compound as 2,2'-azobis- 2-amizinopropane hydrochloride, and about 0.1W100ppm of (c) the above sulfinic acid are dissolved in ion-exchanged water and the polymerization is effected at about 0W40, preferably 10W30°C. This polymerization process can also be applied to the acrylamide copolymerization.
