This invention relates to polymers having non-linear optical properties which polymers include fluorene moieties having at least one electron accepting group and at least one electon donating group substituted to different phenyl rings of the fluorene moiety.

Polymers exhibiting nonlinear optical properties

Compounds having non-linear optical activity of the general formula ##STR1## wherein D and A are electron donor and acceptor groups, respectively, R.sup.1 and R.sup.2 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.

Unsymmetrically substituted fluorenes for non-linear optical applications

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.

Polymeric anti-reflection coatings and coated articles

Solid bodies having a reflective surface are provided with an anti-reflection coating of a 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.

Fluoropolymer blend anti-reflection coatings and coated articles

Azo-type optically active compounds and polymers are provided based on compounds of the general structure

Electro-optical materials and light modulator devices containing same

Solid bodies having a reflective surface are provided with an anti-reflection coating of a fluoropolymer blends of (1) a terpolymer composition derived from (a) perfluoroalkylakyl acrylate or methacrylate, (b) acrylic, methacrylic or itaconic acid, and (c) hydroxyl- containing acrylate or methacrylate; and (2) an amorphous fluoropolymer.

Blends of amorphous fluoropolymers with copolymer compositions derived form (a) perfluroalkylalkyl acrylate or methacrylate, (b) acrylic, methacrylic or itaconic acid, and (c) a hydroxyl-containing acrylate or methacrylate, in combination, can be cured to form coatings having properties typical of fluorine-containing polymers, with unusually low critical surface energy.
