Processes for the production of polymers by emulsion polymerization of olefinically unsaturated monomers, in which olefinically unsaturated esters corresponding to formula (I):HOOC&#x2014;CH&#x2550;CH&#x2014;COO&#x2014;(BO)(PO)(EO)R&#x2003;&#x2003;(I)in which Ris an alkyl group or alkenylphenol group containing 8 to 24 carbon atoms, BO is a butylene oxide unit, PO is a propylene oxide unit and EO is an ethylene oxide unit and the indices x, y and z independently of one another stand for 0 or for numbers of 1 to 50, with the proviso that at least one of the indices x, y and z is not 0, the carboxyl group of the compounds (I) being completely or partly present in neutralized form and the C&#x2550;C double bond being cis- or trans-configured; are used as copolymerizable emulsifiers.

Copolymerizable emulsifiers and emulsion polymerization processes using the same

Processes for producing polyester amides, by reacting a polyisobutylene with a first reagent selected from the group consisting of at least monounsaturated acids having from 3 to 21 carbon atoms and derivatives thereof; and a second reagent selected from the group consisting of monoethanolamine and alkylamines of the general formula R&#x2014;NH, wherein R represents an alkyl group having from 1 to 4 carbon atoms; are described. The polyester amides thus produced and their uses in stabilizing asphaltenes in crude oil and crude oil derivatives are also described.

Process for removing solid asphalt residues produced in the petroleum industry

A process for breaking an emulsion into a water phase and an oil phase involving: (a) providing an emulsion containing an oil phase and a water phase; (b) providing an alkoxylated C,carboxylic acid ester derived by the addition of ethylene oxide and/or propylene oxide onto a ring opened epoxidized C,carboxylic acid triglyceride which is ring opened with a C,carboxylic acid; and (c) contacting the emulsion with a demulsifying effective amount of the alkoxylated C,carboxylic acid ester. Said process has application on crude oil emulsions.
