ABSTRACT:
Novel 3-ring tetraglycidates having the formula ##STR1## wherein ##STR2## Y=halogen, C.sub.1 -C.sub.4 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.
