Unprecedented Acid-Promoted Polymerization and Gelation of Acrylamide: A Serendipitous Discovery.

Dilute acid polymerizes degassed, aqueous acrylamide with concomitant gelation, without the need for added free radical initiator or cross-linking agent. This reaction is accelerated by sonication or UV irradiation, but inhibited by adventitious oxygen or the addition of a free radical inhibitor, suggesting an acid-accelerated free radical process. The… CONTINUE READING
