    • Structured polymer layers having nonlinear optical properties are produced by a process wherein either organic compounds containing ethylenically unsaturated groups are subjected to free radical copolymerization (A) with stilbene, azo or azomethine compounds containing ethylenically unsaturated groups and donor and acceptor groups, or organic compounds containing ethylenically unsaturated groups are subjected to free radical polymerization and are mixed (B) with stilbene, azo or azomethine compounds containing ethylenically unsaturated groups and donor and acceptor groups, the copolymers (A) or mixtures (B) thus obtained are exposed imagewise to high-energy radiation, the unexposed parts are removed and the structured polymer layers thus obtained are polarized in an electric field for orientation of the chromophoric structural units in the region of the glass transition temperature of the polymer and crosslinked in an applied electric field.Such structured polymer layers are suitable for the production of polymeric waveguides in communications technology.
    • 具有非线性光学性质的结构化聚合物层通过一种方法制备,其中含有烯键式不饱和基团的有机化合物与含有烯属不饱和基团和供体和受体基团的二苯乙烯,偶氮或偶氮甲碱化合物或含有 烯键式不饱和基团进行自由基聚合,并与(B)与含有烯键式不饱和基团和供体和受体基团的二苯乙烯,偶氮或偶氮甲碱化合物混合(B),由此获得的共聚物(A)或混合物(B) 能量辐射,去除未曝光部分,并且由此获得的结构化聚合物层在电场中极化,以在聚合物的玻璃化转变温度区域内发色团结构单元的取向并在施加的电场中交联。 这种结构化聚合物层适用于在通信技术中生产聚合物波导。
