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.

Demulsifier compositions and methods of preparation and use thereof

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.

Demulsifier composition and method of use thereof

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:

Vinyl-type interpolymers and uses thereof

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:
