    Abstract: The present invention is directed to epoxy-based polymeric nonlinear optical materials in which a nonlinear optical active moiety or functionality forms the crosslink between polymer chains and a process for making the nonlinear optical (NLO) epoxy polymer including heating an epoxy resin and a curing agent such as a bi- or tri-functional aromatic amine containing an electron-withdrawing group, for example, diamino diphenylsulfone and poling the mixture under high voltage at elevated temperature for a period of time to bring about orientation of the nonlinear optical moieties in the polymer. The polymers have enhanced stability over polymers in which only one end of an NLO active moiety is attached to the polymer chain.
