Progress in elaboration of nonisocyanate polyurethanes based on cyclic carbonates
In the article is given a review on production and application nonisocyanate polyurethanes based on cyclic carbonate oligomers. Nonisocyanate polyurethane (NIPU) networks are obtained by reaction between the polycyclic carbonate oligomers and aliphatic or cycloaliphatic polyamines with primary amino groups. This forms a crosslinked polymer with β-hydroxyurethane groups of different structure - polyhydroxyurethane polymer. Considered as a proper NIPU and hybrid polymers, involving various other oligomeric systems (HNIPU). Significant attention was paid to the materials based on renewable raw materials.The authors give an overview of recent publications in the field with a more detailed description of the Polymate Ltd. achievements.
