Molecular weight and microstructure controlled poly(N-cyclohexyl-5-norbornene-2,3-dicarboximide)s have been synthesized through ring opening metathesis polymerization. These materials were employed as electro-optic (EO) polymer hosts for high molecular hyperpolarizability chromophores. Polymer having 98% trans microstructure exhibited enhanced EO activity after poling at elevated temperatures, showing an EO coefficient of 93 pm/V. Temporal stability of EO activity was confirmed due to the high-Tg property of the polymer host.
