摘要
The anionic polymerisation of epsilon-caprolactam (epsilon-CL) in the presence of bifunctional N-substituted biscarcarbamyl lactams: hexamethylen-dicarbamyl-dicaprolactam (C-X), and 1-isocyanat 3,3,5 trimethyl-5 methyl cyclohexyl-carbamyl-caprolactam (C-I) was studied. They accelerated the polymerization process and did not cause its poisoning. The kinetics of the polymerization in the presence of both additives was investigated and the activating energy were determined. Their activating effect was compared with the most widely used acylcaprolactam (AL). The different action of C-X C-I were explained by their structural difference. (C) 1998 Elsevier Science Ltd.
