Zusammenfassung:	An epoxy resin composition comprises the cured reaction product of an epoxy base resin and a curing agent mixture. The curing agent mixture comprises an amino curative and a polyoxyalkylene polycarbonate. Liquid epoxy base resins cured with polyoxyalkyleneamines in the presence of polyoxyalkylene polycarbonates were harder and displayed improved tensile modulus, flexural strength and flexural modulus.
