Abstract

Pyrrolidone is polymerized at a temperature not exceeding 80 DEG C., in the presence of an alkaline polymerization catalyst, an activator for the polymerization which contains an acyl group or an isocyanate group, and about 0,05 to 3 mole per cent hexamethylene diamine, based on the pyrrolidone monomer. Specified alkaline polymerization catalysts are the alkali metals and oxides, hydrides, hydroxides and amides thereof and quaternary ammonium bases. Specified activators are acetyl pyrrolidone, adipoyl dipyrrolidone, acetyl chloride, stearoyl pyrrolidone, phenyl isocyanate, naphthyl isocyanate, p-phenylene diisocyanate, n-propyl isocyanate, hexamethylene diisocyanate, benzene-1:3:5-triisocyanate, toluylene diisocyanate and p-ethoxyphenyl isocyanate. The examples describe the polymerization of pyrrolidone in the presence of potassium hydroxide, hexamethylene diamine and adipoyl dipyrrolidone or phenyl isocyanate and the purification of the product.
