The article reviews production and application of the nonisocyanate polyurethanes based on cyclic carbonate oligomers. Nonisocyanate polyurethane (NIPU) networks are obtained by the reaction between the polycyclic carbonate oligomers and aliphatic or cycloaliphatic polyamines with primary amino groups. The result is a crosslinked polymer with β-hydroxyurethane groups of different structure defined as a polyhydroxyurethane polymer. The article discusses NIPU and hybrid NIPU (HNIPU), which also contains epoxy and acrylic compounds. Significant attention was paid to the formation of the materials based on renewable raw materials. The authors provide an overview of the recent publications in this field with a more detailed description of the Polymate Ltd. achievements.
