Abstract

754,944. Polymerizing pyrrolidone. HOFFMAN & CO., Inc., A. Feb. 24, 1954 [June 24, 1953], No. 5402/54. Class 2 (5). Pyrrolidone is polymerized in the presence of a polymerization catalyst and an acyl compound as activator while suspended in an organic liquid which is a non-solvent for pyrrolidone. The polymer is obtained as a powder. Suitable activators are acyl anhydrides, alkyl esters, lactones and acyl pyrrolidones used in a concentration of from 0.001 per cent to 25 per cent by weight of the pyrrolidone ; 30 parts non-solvent are preferably used per 10 parts pyrrolidone. The catalysts are as disclosed in Specification 731,294 and the preferred polymerization temperatures are 20- 50‹ C. In an example, 1.5 grams of potassium were added to 101 grams pyrrolidone suspended with agitation in 300 c.c. dry petroleum ether, followed by 1 gram adipyl dipyrrolidone dissolved in 5 c.c. pyrrolidone. Polymerization occurred immediately, the 44 grams of resulting polymer being separated, washed with water and acetone and dried. Specification 749,332 is also referred to.
