HYBRID EPOXY-AMINE HYDROXYURETHANE-GRAFTED POLYMER

摘要

Described is a linear hybrid epoxy-amine hydroxyurethane-grafted polymer with the following structure of the polymer backbone unit:;;where R′ is a residue of a diglycidyl ether (epoxy resin); R1 is a residue of a di-primary amine; R2 and R3 are residues of monocyclic carbonate and are selected from the group consisting of H, alkyl C1-C2, and hydroxymethyl; and at least one of R2 and R3 is hydrogen. The described polymer may be used in manufacturing of liquid leather materials.
