Popis:	N-Benzyl-3-methylenepyrrolidin-2-one (3) was synthesized and homopolymerized under free radical conditions. The configurational microstructure of poly(N-benzyl-3-methylenepyrrolidin-2-one) (4) is isotactic with a minor tendency to syndiotacticity. Monomer 3 was also homopolymerized in water in the presence of methylated β-cyclodextrin. The glass transition temperature of 4 of 124 °C was compared with the lower value of 61 °C of the ring-opened analogue poly(N-benzyl-N-ethylacrylamide). © 2015 Society of Chemical Industry
