    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: 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: 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.
