DOI: dx.doi.org/10.14314/polimery.2003.239


Summary

Mechanism of action of various catalysts, used in the process of isocyanates cyclotrimerization, is presented in the review. The activities of the catalysts (among others industrial ones) have been compared. Especially the catalysts such as tertiary amines, metaloorganic compounds and alkali metal carboxylates were discussed in details.


Keywords: cyclotrimerization of isocyanates, cyclopolymerization of isocyanates, catalysts, mechanism of action
