Abstract: The present disclosure relates to renewable composites as high oxygen and high moisture barriers for packaging. In certain embodiments, the renewable composite comprises cellulose nanocrystals (CNC) and chitin (Ch). In other embodiments, the renewable composite comprises CNC. Ch. and one or more cross-linkers.

Abstract: An electro-optic display comprises a layer of solid electro-optic material; a backplane comprising at least one electrode; and an adhesive layer disposed between the layer of electro-optic material and the backplane and adhesively securing the layer of electro-optic material to the backplane, the adhesive layer comprising a thermally-activated cross-linking agent comprising an epoxidized vegetable oil fatty acid or an epoxidized ester of such a fatty acid. The cross-linking agent reduces void growth when the display is subjected to temperature changes.

Abstract: A polyurethane is formed from an isocyanate and a polyester diol having a molecular weight less than about 2000, or a polyester diol comprising two polyester diol segments connected by a steric hindrance group, each of the polyester diol segments having a molecular weight less than about 2000. The polyurethane is useful as a binder in electro-optic displays, and in components used to form such displays.

Abstract: The invention provides a polishing pad comprising sintered particles of a thermoplastic resin, wherein a surface of the polishing pad intended to contact a substrate to be polished comprises (a) a non-patterned portion with a substantially uniform density and (b) a patterned portion with one or more densities that differ from the density of the non-patterned portion. The invention also provides a method for producing the polishing pad, a chemical-mechanical polishing apparatus comprising the polishing pad, and a method of polishing comprising contacting a substrate with the polishing pad.

Abstract: A method for the alkylsulfonation of polymeric and cyclic trimer phosphazenes that includes reacting the phosphazene with a sultone. This method can be used to prepare sulfonated phosphazenes that are useful as biomedical materials, membranes, reversibly cross-linkable polymers, surfactants, and polyelectrolytes.
