摘要： Polymers are provided that are derived from at least (A) N-vinyl formamide, (B) one vinyl amide moiety or one acrylamide moiety, and (C) a reaction solvent. The polymers are random, block, or alternating polymers. A particular useful poly-mer comprises about 20% N-vinyl formamide, about 50% N-vinyl-&egr;-caprolactam, about 30% N-vinyl-2-pyrrolidone, being synthesized in ethylene glycol. In preferred embodiments, polymers of the invention exhibit a cloud point temperature of 66° C. or more, inhibit the formation of gas hydrates, and/or inhibit corrosion. Especially preferred uses of the polymers are in oilfield operations as gas hydrate inhibitors and/or corrosion inhibitors.

摘要： A composition comprising a long-chain alkylpyrrolidone, a surfactant, and film-forming water-soluble polymer wherein the amounts of the components are such that on dilution with water, a clear liquid is formed. The composition may be used as a medium for agriculturally active ingredients as well as other active ingredients which are suitable for film formation, e.g., wood protectants, and the like. Also, emulsion concentrates of water-insoluble film-forming polymers are disclosed which can be utilized to form water-resistant films of active ingredients, such as, agriculturally active chemicals. Methods for preparation and use of the emulsion concentrates are disclosed.

摘要： A stable wetting concentrate includes octyl or dodecyl pyrrolidone, an ethoxylated alcohol, and a compatabilizing agent for dilution of the concentrate with water, suitably a polar material, such as an anionic emulsifier, or polyol, which prevents separation of the two base components in water, and, optionally, water, provides a stable wetting composition upon dilution with water, which exhibit superior wetting and spreading properties.
