Reaction products of olefinically unsaturated carboxylic acids and

Petroleum emulsion breakers based on alkoxylated polyethyleneimines are obtained by reacting polyethyleneimine with a molecular weight of 2,500-35,000 with 5-40 moles each of propylene oxide and ethylene oxide per ethyleneimine unit in the polyethyleneimine and are used for the demulsification of petroleum emulsions at from 10.degree. C. to 130.degree. C.

Petroleum emulsion breakers

Oil demulsifiers are based on an alkoxylate having a polydispersity of at least 1.7, and the alkoxylates are prepared using a metal alcoholate as a catalyst.

Fuels containing small amounts of alkoxylates and polycarboximides

This invention relates to aliphatic or aromatic polycarboxylic acid esters as defined herein which are useful as base oils alone in lubricating oil compositions or in admixture with completely synthetic, partially synthetic, or mineral oil-based lubricant compositions.

Polycarboxylic acid esters and lubricants containing these esters

Compression moldings are produced from finely divided thermoplastic polymers by a method in which the polymer particles are mixed with an effective amount of amorphous silica before being subjected to compression molding. Compression moldings of this type are used for the preparation of finishes, paints and lubricating oils, depending on the type of the polymers.
