Abstract
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.
