摘要： The present invention relates to a middle-pressure polymerization process for the preparation of a liquid ethylene copolymer which comprises in polymerized form 20 to 60 wt % of ethylene; and at least 20 wt % of an acrylate, which is selected from C1-C22 alkyl (meth)acrylate, where a monomer mix comprising the ethylene and the acrylate is polymerized at a pressure of 50 to 400 bar and in the presence of at least 2 wt % of a chain transfer agent. The invention further relates to a liquid ethylene copolymer obtainable by the polymerization process; and to a lubricant comprising the liquid ethylene copolymer obtainable by the polymerization process; and to a method for reducing friction between moving surfaces comprising the step of contacting the surfaces with the lubricant or with the ethylene copolymer.

摘要： Fluid compositions comprised of a monomer constituent dissolved in a carrier fluid, where the monomer constituent is capable of forming a polymer film directly on rubbing surfaces but is not polymerized in solution, have been found to be effective for reducing ceramic wear.

摘要： Embodiments herein relate to polyacrylic acid containing lubricious coatings for medical devices. In an embodiment, a lubricious coated medical device is included having a substrate and a first layer disposed over the substrate. The first layer can include a photoreactive polyvinylpyrrolidone, a non-photoreactive polyvinylpyrrolidone, and a crosslinking compound. A second layer can be disposed over the first layer, the second layer can include a poly(acrylic acid), and a non-photoreactive polyvinylpyrrolidone. The non-photoreactive polyvinylpyrrolidone of the second layer forms a complex with the poly(acrylic acid) of the second layer. The non-photoreactive polyvinylpyrrolidone of the second layer has a concentration existing as a gradient through a thickness of the second layer with a lower concentration at an outer surface of the second layer than at an inner surface of the second layer. Other embodiments are also included herein.
