ABSTRACT:
Novel nonlinearly optically active polymers, well suited for electrooptical applications, are prepared by copolymerizing a first difunctional monomer with a second difunctional comonomer, with at least one of such difunctional monomers including a polar charge transfer moiety containing at least one electron acceptor group and at least one electron donor group (D), and further wherein the polymerizable functional groups are borne by the one or more electron donor groups (D).
