Synthesis and application of nonisocyanate polyurethanes
The latest published achievements in the research and developments of non-isocyanate polyurethanes on the base of five-membered cyclic carbonates and amines are briefly presented. Preparations of hybrid epoxy-amine hydroxyurethane-grafted polymers with a controlled number of cross-links are described. Examples of the use of hydroxyurethanes of different nature for modification of the oligomeric compositions are also given.
