✦ Synopsis

Synthesis and properties of epoxyfumarate and epoxymaleate resins obtained by the addition of acidic benzyl maleate to the commercially available epoxy resin are presented. The resins were synthesized in one-and two-step procedures. In the two-step procedure, acidic benzyl maleate was synthesized separately and then used for the addition reaction with epoxy resin, Epidian 5. In the one-step procedure, acidic ester was formed during the synthesis process. Properties of the resins in a noncrosslinked state, during curing, and after crosslinking were compared.
