The synthesis of pyrrolidone-N-sulfonyl chloride has been carried out by the reaction of pyrrolidone with sulfuryl chloride in benzene. It was attempted to study the catalytic effect of pyrroldone-N-sulfonyl chloride as an initiator for anionic polymerization of pyrrolidone. It was found that as a concentration of initiator decreased, inherent viscosity of the resulting polymer increased up to 1.8 dl/g. The highest rate of polymerization and equilibrium conversion was observed when mole ratio of PNSC to KOH was 0.25. In general, the observed value of polymerization and equilibrium conversion in circumstances using PNSC/KOH catalysis system were higher than using CO2/KOH catalysis system.
