摘要：

Novel epoxy resins containing zinc, chromium and copper have been synthesized by reacting acrylates of these metals with bisphenol-A and excess epichlorohydrin. Parameters, such as epoxide equivalent weight, hydroxyl content and viscosity, increase as a function of concentration of metals. The resins, characterized by i.r., SEM, n.m.r., C-13 n.m.r. and cured with polyamide at room temperature for 24 h and 80-degrees-C for 2 h, have improved thermal stability, chemical resistance and electrical conductivity as compared to unmodified epoxy resin. The results have been explained by the assumption that the metal(s) form a complex with bisphenol-A.
