ABSTRACT:
The present invention is directed to an epoxy-containing polymeric material having nonlinear optical properties, particularly a glycidyl amine polymer, and a process for making the nonlinear optical (NLO) epoxy-containing polymeric material including poling the polymeric material under high voltage at elevated temperature for a period of time to bring about orientation of the nonlinear optical functionalities in the polymer. The polymers have enhanced thermal stability and good NLO properties.
