The present invention provides polyurethanes including a reaction product of components including: (a) an isocyanate functional urethane prepolymer comprising a reaction product of components including: (i) about 1 equivalent of at least one polyisocyanate; and (ii) about 0.1 to about 0.5 equivalents of at least one diol having 2 to 18 carbon atoms; and (b) about 0.05 to about 0.9 equivalents of at least one branched polyol having 4 to 18 carbon atoms and at least 3 hydroxyl groups; and (c) up to about 0.9 equivalents of at least one polyol different from branched polyol (b) and having 2 to 18 carbon atoms, wherein the reaction product components are essentially free of polyester polyol and polyether polyol; compositions, coatings and articles made therefrom and methods of making the same.

The present invention relates to an improved formaldehyde-free coated fibrous substrate. The coating includes a crosslinked binder system which forms three dimensional networks when heat cured. After the coating is applied to the back of fibrous substrate and cured, the coating is capable of hygroscopic expansion which imparts excellent anti-sag properties. The coating is compatible with other coating systems with neutral or mild alkaline pH. The improvement being the binding system is neutralized with a volatile base so that it evaporates quickly so as not to hinder the cross-linking reaction.

The present invention relates to filled polymeric materials including a polymer and a mass of metallic fibers distributed within the polymer, and to light weight composites which comprise at least a pair of metallic layers and a polymeric layer interposed between the pair of metallic layers, the polymeric layer containing the filled polymeric material. The composite materials of the present invention may be formed using conventional stamping equipment at ambient temperatures. Composite materials of the present invention may also be capable of being welded to other metal materials using a resistance welding process such as resistance spot welding. Preferred composite materials include one or any combination of the following features: metallic fibers that are ribbon fibers; a polymer selected from a polyolefin, a polyamide, or a combination thereof; or a metallic layer (e.g., one or both of the pair of metallic layers) having a surface facing the filled polymeric material that is untreated.

Disclosed herein is a polyhydroxy ketal adduct obtained by the esterification of a hydrocarbon polyol by at least 1.5 equivalents of a ketocarboxy to produce an intermediate ketocarboxylic ester. The intermediate polyketocarboxylic ester is then ketalized to produce the polyhydroxyketal adduct, which can be used to provide a polymeric composition.

A protective sheet includes a base layer, an interfacial layer, and a skin layer stacked in order. The base layer includes an aromatic polycarbonate resin, the interfacial layer includes an aliphatic polycarbonate resin; and the skin layer includes a cycloolefin polymer (COP) resin.

Provided are novel cross-linked polymers and their use in various materials, including packaging films and injection molded articles. These polymers, which comprise certain hydroxyl-containing crosslinking compounds, as well as optionally adjuvants, show improved creep resistance when compared to conventional ethylene acrylic or methacrylic acid copolymers and their ionomers.

A method for depositing a coating comprising a polymer and pharmaceutical agent on a substrate, comprising the following steps: discharging at least one pharmaceutical agent in a therapeutically desirable morphology in dry powder form through a first orifice; discharging at least one polymer in dry powder form through a second orifice; depositing the polymer and/or pharmaceutical particles onto said substrate, wherein an electrical potential is maintained between the substrate and the pharmaceutical and/or polymer particles, thereby forming said coating; and sintering said coating under conditions that do not substantially modify the morphology of said pharmaceutical agent.
