Abstract

Anionic catalytic polymerisation of lactam(s) is in presence of di-phenyl-N-methylimino esters as promoter. The catalyst is pref. lactam-N-anions obtd., e.g. from a lactam-metal cpd. with a metal atom on the N, e.g. Na caprolactam. Pref. amt. is 5-10 (0.1-5) mols.% w.r.t. monomer(s). Promoters include di-phenyl-N-methylimino acetate (I), and the di-phenyl-N-methylimino-diester of sebacic acid. The amt. is esp. 0.1-2 mols.% w.r.t. lactam(s). Pref. lactams are 4-16C. Pref. polymerisation is at 90-250 deg.C., esp. at an initial temp. of 90-150 deg.C. with an increase to 200-215 deg.C. Solid polyamides are obtd. in short polymerisation times (esp. less than 10 mins.). Polymerisation at between the m.pt. of the lactam and the m.pt. of the polymer gives a moulded shape corresp. in dimensions to the reaction chamber.
