    摘要： Applicant has discovered an in situ method of preparing quaternary ammonium methocarbonate salts and quaternary ammonium alkylcarbonate salts in high yield from tertiary amines, methanol, and at least one of a cyclic carbonate, an aliphatic polyester (such as a polycarbonate), or an ester (such as a carbonate ester), and their subsequent conversion to quaternary ammonium bicarbonates, quaternary ammonium carbonates or both in a one-pot reaction. According to one embodiment of the invention, the method includes reacting an amine and methanol with at least one of a cyclic carbonate and an aliphatic polyester to yield a quaternary ammonium methocarbonate. This method does not produce or require the handling of corrosive quaternary ammonium hydroxides. Another embodiment is a method of preparing quaternary ammonium alkylcarbonate salts by reacting tertiary amines, methanol, and an ester. The quaternary ammonium methocarbonate or alkylcarbonate can be converted to the corresponding bicarbonate, carbonate, or mixture thereof by methods known in the art.

    摘要： Applicants have discovered that amine oxides enhance the uniform distribution and penetration of wood preservatives into wood substrates, minimize leaching of the wood preservatives, and improve the weatherability of the wood substrate. The present invention provides a method for enhancing the uniform distribution and penetration of at least one wood preservative into a wood substrate by applying a preservative composition to the wood substrate. The preservative composition comprises a wood distribution and penetration enhancing agent, which includes an amine oxide, and the wood preservatives. Another embodiment of the present invention is a method for enhancing the uniform distribution and penetration of one or more wood preservatives by applying the wood preservatives to the wood substrate and then applying the aforementioned wood distribution and penetration enhancing agent to the wood substrate. Alternatively, the wood distribution and penetration enhancing agent may be applied prior to application of the wood preservatives or both may be applied concurrently. Yet another embodiment is a preservative composition comprising a wood distribution and penetration enhancing agent and at least one wood preservative. Preferably, the composition comprises a uniform distribution and penetration enhancing effective amount of the wood distribution and penetration enhancing agent and a wood preserving effective amount of the wood preservative.

    摘要： The present inventors have discovered that amine oxides are highly effective as wood preservatives. The present invention provides a wood preservative composition comprising a biocidally effective amount of one or more amine oxides. Preferably, the wood preservative composition is substantially free of halogenated compounds (such as halides and chlorinated compounds) and quaternary ammonium compounds. The wood preservative composition of the present invention exhibits low toxicity, high stability in water, low corrosivity to metal substrates (such as steel substrates), excellent penetration and uniform distribution into wood, low odor, waterproofing properties, and high leaching resistance. The wood preservative composition may be applied to the surface of a wood substrate or be applied by pressure treating the wood substrate with the wood preservative composition. Other cellulosic and fiber materials, such as cotton, burlap, and like materials, may be preserved with the composition of the present invention. Another embodiment is a method of controlling microorganisms, such as fungal decay organisms (generally known as white rot, brown rot, and soft rot fungi) and sapstain organisms, on and/or in a wood substrate, such as fresh cut lumber, comprising applying a biocidally effective amount of the composition of the present invention to the wood substrate.

    摘要： Graft polymers are prepared by reacting an ethylenically unsaturated polymerizable monomer with a polymer of an olefin of 2 to about 8 carbon atoms in a process wherein the olefin polymer is substantially insoluble in the monomer but is capable of absorbing the monomer. In a preferred aspect, a vinyl halide polyolefin graft polymer is produced by reacting a solid polyolefin particle with a vinyl halide monomer in which the polyolefin is substantially insoluble, but is capable of absorbing the monomer. The solid particles can be contacted with the monomer in one step or in stages. When the stage-wise reaction is continued until the proportion of polyolefin in the polymer product is about 2 to about 20 weight percent, the resulting product can be formed to a transparent or translucent article. When a small proportion of solid polyolefin is employed in the polymerization process, both a graft polymer and a polymer of the unsaturated monomer are simultaneously produced in the same reactor and can be readily mechanically separated into the individual products.
