Popis: 1. The vinylation of lactams was studied, the examples taken being the vinylation of 2-pyrrolidinone, 2-piperidone, and caprolactam. Alkali-metal salts of the lactams were used as catalysts. It was found that the most convenient method of preparing these salts is direct reaction between the lactams and alkali metals. It was shown that water has an unfavorable effect on the course of the vinylation. 2. It was shown that, like other N-vinyl lactams, 1-vinyl-2-piperidone is hydrolyzed in an acid medium; optimum hydrolysis conditions were determined. 3. The polymerization of N-vinyl lactams was carried out in presence of 2,2′-azobis[2-methylpropionitrile], and also in presence of hydrogen peroxide in aqueous solution. The copolymerization of 1-vinyl- 2-piperidone with methyl methacrylate was carried out.
