Alternating copolymerization of 2-methyl-2-oxazoline with α-chloro- and α-bromoacrylic acids: 3. Synthesis, characterization and kinetics

Add time:08/01/2019    Source:sciencedirect.com

New 1:1 alternating copolymers of 2-methyl-2-oxazoline with (i) α-chloroacrylic acid and (ii) α-bromoacrylic acid were synthesized and characterized by i.r., n.m.r. and the products of alkaline hydrolysis. The copolymerization occurred at a temperature of 60°C without any added catalyst or initiator. The copolymerization kinetics were studied and the order with respect to each monomer was found to be unity. A scheme for the copolymerization involving a zwitterion intermediate is proposed.
