    摘要： A water soluble copolymer of polymerizable esters of unsaturated carboxylic acids having the hydrazide group as a substituent comprises a major proportion of monomer units which are methyl acrylate and/or methyl methacrylate and a minor proportion of co-monomer units which are one or more alkyl esters of acrylic acid or methacrylic acid wherein the alkyl group comprises at least four carbon atoms. The copolymer has film forming properties which make it useful for use in protective coatings. The invention includes a film forming composition comprising the copolymer and a cross-linking agent which cross-linking agent is an aldehyde or an organic thermosetting resin containing methylol or methoxy groups, the copolymer and cross-linking agent being dissolved in an aqueous medium in amounts such that they will form a film when applied to a surface. The composition is applied to a surface and heated at 120.degree. to 180.degree. C. for from 5 mins to 4 hours to produce a water insoluble coating from a water based composition containing the water soluble copolymer.

    摘要： A method of treating salt water-in-oil dispersions comprises mixing with the dispersion a latex of a rubber having a high wet gel strength. The incorporation of the latex into the dispersion causes exudation of water from the dispersion with resulting thickening. If sufficient latex is used the dispersion may be transformed into a solid. Suitable rubbers include natural rubber, polychloroprene rubber, butadiene acrylonitrile rubber, styrene butadiene rubber and poly (methyl methacrylate) graft natural rubber.The tackiness of solids formed using for example a natural rubber latex can be reduced by using in addition to the natural rubber latex, a latex of a low or zero wet gel strength polymer e.g. PVC, poly (vinyl acetate) or polystyrene. The effectiveness of the method of treatment may be improved by the use of a suitable compatible solvent e.g. toluene or a filler such as a clay filler.

    摘要翻译： 盐水包油分散体的处理方法包括与分散体混合具有高湿凝胶强度的橡胶的胶乳。 将胶乳掺入分散体中会导致水分散，从而产生增稠。 如果使用足够的胶乳，则可将分散体转变成固体。 合适的橡胶包括天然橡胶，聚氯丁二烯橡胶，丁二烯丙烯腈橡胶，苯乙烯丁二烯橡胶和聚（甲基丙烯酸甲酯）接枝天然橡胶。 使用例如天然橡胶胶乳形成的固体的粘性可以通过使用天然橡胶胶乳，低或零湿凝胶强度聚合物的胶乳，例如， PVC，聚（乙酸乙烯酯）或聚苯乙烯。 治疗方法的有效性可以通过使用合适的相容溶剂，例如， 甲苯或填料如粘土填料。
