Epoxy resins based on tetraglycidyl diamines

Novel 3-ring tetraglycidates having the formula (I) wherein Y=halogen, C1-C4 alkyl; and n=0 to 4, are disclosed. Epoxy resin systems exhibiting good tensile properties and moisture sensitivity can be made by copolymerizing the tetraglycidates with a polyamine curing agent. Prepregs can be made by co...

Zusammenfassung:	Novel 3-ring tetraglycidates having the formula (I) wherein Y=halogen, C1-C4 alkyl; and n=0 to 4, are disclosed. Epoxy resin systems exhibiting good tensile properties and moisture sensitivity can be made by copolymerizing the tetraglycidates with a polyamine curing agent. Prepregs can be made by combining the epoxy resin systems with a fiber reinforcement. The epoxy resin system may include a co-epoxide.
