Abstract
This invention provides synthetic routes for novel single isomers of monocarbamate diols and their polymerization to provide novel polyesters, polyurethanes, polycarbonates, and the like having pendant carbamate groups on the polymer chain. Devices using some of these novel polymers which demonstrate nonlinear optical activity are also disclosed.
