Abstract:
A composition that includes a blend of a fluoropolymer and an ultraviolet light-absorbing oligomer. The oligomer has a first divalent unit having a pendent ultraviolet absorbing group and a second divalent unit represented by formula (I): At least one of the following limitations is also met: the ultraviolet light-absorbing oligomer further comprises a third divalent unit comprising a pendent 2,2,6,6-tetramethylpiperidinyl group, or the composition further comprises a second oligomer comprising a third divalent unit comprising a pendent 2,2,6,6-tetramethylpiperidinyl group at least one of the second divalent units. Articles including the composition are disclosed. The composition can be an extruded film. A method of making such an extruded film is also disclosed.
Abstract:
Compositions of matter capable of being cast and cured to form a microreplicated pattern on a substrate, and further capable of swelling on exposure to water so as to release from that substrate. Water swellable acrylic polymers formed from these compositions, and methods of using same in nanoimprint lithography are also disclosed.
Abstract:
Optical films are described having a polymerized microstructured surface that comprises the reaction product of a polymerizable resin composition comprising at least one polymerizable ethylenically unsaturated triphenyl monomer. Also described are certain triphenyl (meth)acrylate monomers and polymerizable resin compositions.
Abstract:
Presently described are optical films, such as a brightness enhancing film, having a polymerized microstructured surface disposed on a preformed polymeric film wherein the film has a thickness of no greater than 3 mils and the polymerized microstructured surface consists of the reaction product of a substantially non-brominated polymerizable resin composition.
Abstract:
Articles include a substrate surface with a layer of indium-tin oxide, and a cured resin layer of less than 25 micrometers thickness at least partially covering the indium-tin oxide layer. The cured resin layer is the cured product of a curable mixture including at least one acid-functional (meth)acrylate, and at least one initiator, and may include additional co-curable monomers and/or crosslinkers. Methods for preparing articles include providing a substrate with a layer of indium-tin oxide, providing a curable resin mixture, contacting the curable resin mixture to at least a portion of the layer of indium-tin oxide at a thickness of 1-25 micrometers; and curing the curable resin mixture. The curable resin mixture may be coated on the layer of indium-tin oxide, or it may be coated onto a processing substrate, and then laminated to the layer of indium-tin oxide.
Abstract:
The present invention provides pressure-sensitive adhesives having a refractive index of at least 1.50. The pressure-sensitive adhesives comprise at least one monomer containing a substituted or an unsubstituted biphenyl group.
Abstract:
Branched polydiorganosiloxane polyamide, block copolymers and methods of making the copolymers are provided. The method of making the copolymers involves reacting one or more amine compounds including at least one polyamine with a precursor having at least one polydiorganosiloxane segment and at least two ester groups.
Abstract:
A method of making optical films having a polymerized microstructured surface are described. The polymerized microstructured surface comprises the reaction product of a polymerizable resin composition comprising 10% to 100 wt-% of at least one biphenyl di(meth)acrylate monomer. The di(meth)acrylate monomer comprises a core biphenyl structure having two aromatic rings connected with a C—C bond. The biphenyl di(meth)acrylate monomer preferably comprises a sufficient amount of ortho and/or meta(meth)acrylate substituents such that the monomer is a liquid at 25° C.
