摘要： Novel demulsifier compositions, their method of preparation and use as demulsifiers are described. The novel demulsifiers comprise the partially condensed reaction product of a blend of at least two oxyalkylated materials with a vinyl monomer. The demulsifiers are useful in the resolution of water-in-oil emulsions.

摘要： A composition comprising the reaction product resulting from subjecting to grafting and esterification reaction conditions a mixture comprising a polyoxyalkylene amine and a vinyl monomer. The mixture is substantially free of copolymers derived from a polyoxyalkylene glycol and a diglycidyl ether, and the reaction product is partially cross-linked. Methods of use and preparation of such compositions are also disclosed.

摘要： This invention relates to vinyl-type interpolymers having an overall carbon/oxygen atom ratio of about 2 to about 4, which is preferably derived from 2 types of vinyl monomers:(1) at least one vinyl-type monomer present in the interpolymer at about 50 mole % or greater and having a carbon/oxygen atom ratio of about 3 or less ("hydrophilic" monomer), and(2) at least one vinyl-type monomer present in the interpolymer at about 50 mole % or less and having a carbon/oxygen atom ratio of about 3 or more ("hydrophobic" monomer).Typical examples are vinyl acetate/vinyl fatty ester copolymers and vinyl acetate/dialkyl maleate copolymers. This invention also relates to uses for these compositions, particularly in the demulsification of W/O emulsions.

摘要： This invention relates to an exothermic emulsion polymerization method characterized by the presence of a low boiling fluid as a component of one of the phases of the emulsion system, said low boiling fluid having the following characteristics:(1) It is sufficiently inert so that it does not interfere with the polymerization reaction(2) It is capable of maintaining by reflux the polymerization system at relatively even and homogeneous temperature.This is exemplified by the use of a halogenated hydrocarbon boiling below about 50.degree. C. as the low boiling fluid.
摘要翻译： 本发明涉及一种放热乳液聚合方法，其特征在于存在低沸点流体作为乳液体系的一个相的组分，所述低沸点流体具有以下特征：（1）足够惰性，使得它 不干扰聚合反应（2）能够在相对均匀且均匀的温度下使聚合体系回流维持。 这是通过使用沸点低于约50℃的卤代烃作为低沸点流体来举例说明的。
