Abstract:
A method of making a polymer by providing an imine and reacting the imine with a polyisocyanate in the presence of a hydroxyl group. The imine is a polyaldimine, hydroxyaldimine, polyketimine, or hydroxyketimines. The polymer has urea linkages formed from the imine and polyisocyanate and urethane linkages formed from the hydroxyl group and the polyisocyanate. The polymer has at least as many urea linkages as urethane linkages. A polymer having urea units and urethane units having a molar ratio of at least about 2:1. A polymer comprising a urea-urethane repeat unit.
