An optical article is disclosed containing, for the transmission of electromagnetic radiation, a medium exhibiting a high second order polarization susceptibility containing a vinyl polymer having backbone pendant carbocyclic aromatic groups susbstituted with polar aligned noncentrosymmetric organic molecular dipoles. The molecular dipoles are linked to greater than 60 percent of the backbone pendant carbocyclic aromatic rings through an ester or amide linkage, so that said medium exhibits a second order polarization susceptibility of greater than 10.sup.-9 electrostatic units and a glass transition temperature in excess of 150.degree. C.
本发明揭示了一种光学物品,用于传输电磁辐射,其中包含一种介质,该介质表现出高二阶极化敏感度,其含有具有主链挂链碳环芳香基团的
乙烯基聚合物,该基团被取代为极性对齐的非中心对称有机分子偶极子。这些分子偶极子通过酯或酰胺键连接到大于60%的主链挂链碳环芳香环上,因此该介质表现出大于10.sup.-9静电单位的二阶极化敏感度和超过150℃的
玻璃转变温度。
