    摘要: The invention relates to novel cinnamamides, a process for their manufacture and their use as UV absorbers. The cinnamamides of the invention may be used as UV absorbers in a variety of engineered resins such as polyamides (especially nylon 6 and 6,6), polycarbonates, polyacetals, polysulfones, polyimides, polyaryletherketones, and polyesters, (especially PET and PBT), as well as, other polymers such as polyvinylchloride and polyolefins (polyethylenes and polypropylenes).

    摘要: Homopolymers and copolymers with an acrylic backbone chain having pendant side-chains containing a nitrone functional group undergo change in refractive index upon exposure to actinic radiation. Waveguides are "written" in films containing such polymers by exposing predetermined areas to sufficient actinic radiation to change the refractive index.

    摘要: Homopolymers and copolymers with an acrylic backbone chain having pendant side-chains containing a nitrone functional group undergo change in refractive index upon exposure to actinic radiation. Waveguides are "written"in films containing such polymers by exposing predtermined areas to sufficient actinic radiation to change the refractive index.
