ScholarBank@NUS Repository.||Abstract:||A novel polymerizable zwitterionic betaine surfactant of acryloyl-undecyldimethylammonio acetate (AUDMAA) was synthesized using acryloyl chloride, 11-bromoundecanol, and glycine. Its critical micelle concentration is 9.42×10-3 mol/L at 24 °C. The polymerization followed first-order kinetics with respect to [AUDMAA] and one-half order with respect to [K2S2O8]. The activation energy for the micellar polymerization of AUDMAA was found to be only 50.2 kJ/mol. The M̄w of poly(AUDMAA) ranged from about 3.0 to 5.0×104 and its MWD was rather narrow (1.8||Source Title:||Journal of Macromolecular Science - Pure and Applied Chemistry||URI:||http://scholarbank.nus.edu.sg/handle/10635/91749||ISSN:||10601325|
