Abstract:
Compounds having non-linear optical activity of general formula (I), wherein D and A are electron donor and acceptor groups, respectively, R and R are aromatic bridging groups, X and Y are preferably groups capable of partaking in polymerization reactions are suitable for use in polymer-based light modulator devices.
Abstract:
Azo-type optically active compounds and polymers are provided based on compounds of the general structure [substituted aryl]-N=N-[substituted aryl] wherein aryl substituents are introduced which hinder or prohibit rotation around the single bonds of the -N=N- central moiety (as well as around certain other single bonds), to provide 'planarized' structures having improved optically active properties, especially electro-optically active properties. These compounds and polymers find use in optically active waveguides.
Abstract:
Fluoropolymer blends of (1) a terpolymer composition derived from (a) perfluoroalkylalkyl acrylate or methacrylate, (b) acrylic, methacrylic or itaconic acid, and (c) hydroxyl-containing acrylate or methacrylate; and (2) an amorphous fluoropolymer are applied to solid bodies having a reflective surface to provide an anti-reflection coating.
Abstract:
Solid bodies having a reflective surface are provided with an anti-reflection coating of a terpolymer composition derived from (a) perfluoroalkylalkyl acrylate or methacrylate, (b) acrylic, methacrylic or itaconic acid, and (c) hydroxyl- containing acrylate or methacrylate.
