| titleOfInvention | Polymerization process using a sodium carboxylactamate catalyst |
| abstract | The polymerization of 2-pyrrolidone is achieved in high yield in the presence of a sodium-derived catalyst activator produced by the reaction of carbon dioxide with the sodium lactamate derived from the reaction of a sodium alkoxide and a 5-7 membered-ring lactam in an inert liquid nonsolvent. |
