摘要：

A high-T(g) polyimide has been synthesized for nonlinear optical studies- The polyamic acid precursor polymer can be efficiently poled and imidized yielding a d33 coefficient of 2.8 x 10(-7) esu. Exceptional dynamic thermal stability was observed up to 185-degrees-C and temporal stability of the nonlinear optical signal at 90-degrees-C is realized for hundreds of hours with insignificant loss of optical activity.
