摘要：An aromatic diamine, CMOMDA, was synthesized and used as a chain extender for reaction injection molding (RIM) polyurethane-urea. The morphology and properties of CMOMDA-, DETDA-, and MDA-extended poly (ether-urethane-urea)s (PEUUs) were measured by IR, DSC, DMS, SEM, and tensile testing apparatus. Well-matched values of C(h) and X(ut,b)/C(h) were necessary for aromatic diamine-extended PEUU. DSC and SEM showed that the aggregation state of hard segments might undergo some changes with increasing hard-segment content. (C) 1994 John Wiley & Sons, Inc.
