AN OPTICAL ARTICLE CONTAINING A LINEAR CONDENSATION POLYMER EXHIBITING A HIGH LEVEL OF SECOND ORDER POLARIZATION SUSCEPTIBILITY ABSTRACT OF THE DISCLOSURE An optical article is disclosed containing, for the transmission of electromagnetic radiation, a medium exhibiting a second order polarization susceptibility greater than 10-9 electrostatic units comprised of a linear polymer containing polar aligned noncentrosymmetric molecular dipoles having an electron donor moiety linked through a conjugated .pi. bonding system to an electron acceptor moiety to permit oscillation of the molecular dipole between a ground state exhibiting a first dipole moment and an excited state exhibiting a differing dipole moment. The linear polymer is a condensation polymer including in its backbone a plurality of molecular dipoles including sulfonyl electron acceptor moieties sequentially arranged to reinforce electron displacement along the polymer backbone.
