Zusammenfassung: | A series of polyoxyalkylene diamines modified with phenoxy groups is disclosed. This series of diamines is of the general formula: wherein R1 and R2 are independently hydrogen or an alkyl of 1 to 4 carbon atoms, R3 is a alkyl of 1 to 4 carbon atoms, Ph is phenyl, x ranges from 2 to 40, y ranges from 1 to 20 and z ranges from 1 to 40. These diamines are cured with liquid epoxy resins. The cured resins demonstrated improved tensile strength and modulus, elongation and flexural strength and modulus over a commercially used curative. The diamines are also useful in RIM elastomers, in polyamides and as chain extenders in polyurethane foams. |
