ABSTRACT:
This invention provides novel polyethers and polycarbonates which exhibit nonlinear optical response, and which have utility as a transparent optical component in optical light switch and high modulator devices.
These polyethers and polycarbonates are the polymerization product of one or more monomers having the formula ##STR1## in which Z is a conjugated heterocyclic substituent having a NO.sub.2 or a CN group. Further, the invention relates to a method of making the polycarbonate by a ring opening polymerization in the presence of an electric field. In a separate embodiment, the invention relates to non-linear optical devices made with these polymers.
