Abstract
Polyurethane/polyurea foams are made by reacting an organic polyisocyanate with resins containing imino/enamino-functional groups in the presence of blowing agents. Control of foam properties is offered by selecting imino/enamino-functional groups which decompose with water at the temperature of the reaction to produce volatile gases.
