PCT No. PCT/FR94/00767 Sec. 371 Date Oct. 28, 1996 Sec. 102(e) Date Oct. 28, 1996 PCT Filed Jun. 24, 1994 PCT Pub. No. WO95/00571 PCT Pub. Date Jan. 5, 1995The invention relates to a crosslinkable polymer for use in optics and non-linear optics, which comprises at least one chromophore, characterized in that it has, on at least two of its ends, at least one reactive end group of a different chemical type from the group predominantly used in polymerization and the preparation of a polymer skeleton. Said reactive end group comprises at least one CC, CN, CS, SS or NS double bond and/or triple bond, and/or an epoxy group and/or a thiol group or a derivative of said groups, and the polymerization groups are selected from at least one of the following groups: urethane, ester, amide, imide, ether, carbon-carbon, sulfide, silane and siloxane, urethane and ester groups being particularly preferred. Application in optical and opto-electronic materials and devices.
