摘要

The present invention relates to polymers active in nonlinear optics, characterised in that they are obtained by reaction of a first difunctional compound with a second difunctional compound, at least one of the difunctional compounds comprising a charge transfer polar group containing at least one electron-acceptor group, at least one electron-donor group (D) and in that the functional groups which are reactive in the case of the polymerisation are carried by the electron-donor group(s).
