    • The present invention relates to a new polyesterimide of the type containing ester repeat functional groups E=--CO--O--, imide repeat functional groups I: ##STR1## and at least one chromophore, characterized in that it contains a quantity of recurrent amide functional groups capable of ring closure to imides which is smaller than or equal to 5 mol % relative to the sum of the imide functional groups and of the amide functional groups capable of ring closure to imides, which are present, and in that the polymerization functional groups consist essentially of E functional groups. This polyesterimide is preferably free from amide functional groups capable of ring closure to imides. One of the processes for obtaining this polyesterimide constitutes another subject-matter of the invention. Such a polymer is advantageously capable of behaving like a material that is transparent and/or active in nonlinear optics. It therefore constitutes a raw material of choice for producing LO and/or NLO devices: filters, polarizers, waveguides, a modulator, directional coupler, optical flip-flop and photoconductive film.
