Abstract
Abstract A thermally curable system containing DπA groups can be poled by an electrical field while, simultaneously, the system is cured. Thus favourable NLO-waveguides can be obtained. The disclosed systems comprise a DπA group containing compound (A) having two or more functional groups and a compound (B) having two or more functional groups reactive towards (A). Essentially, one of the components (A) or (B) contains isocyanate groups. To obtain a polymeric network at least one of the compounds (A) or (B) should be tri-or higher functional.
