Compositions produced from dicarboxylic acids esters of alpha, beta-olefinically unsaturated compounds which are particularly unsaturated suitable for use as lubricants and lubricant additives, and process for preparing such compositions.

摘要

ACCORDING to the present invention, there is provided a composition comprising the reaction product of in particular (1) ESTERS dicarboxylic acids UNSATURATED ALPHA BETA, Y (2) Unsaturated compounds olefinically IN WHICH the resulting composition comprises a substantial amount of A reaction product INTERMEDIATE MOLECULAR WEIGHT IS NOT KNOWN alkenyl, MOLECULAR WEIGHT LOWER OR THE rEACTION PRODUCT alkyl succinic, NEITHER THE PRODUCT KNOWN polymerization reaction, DE (1) and (2). The compositions of the present invention are particularly suitable for use as lubricants and additives lubricants. ACCORDING TO THE INVENTION THIS, ALSO INTRODUCES for preparing such compositions suitable for use as lubricants or lubricant additive process, wherein components (1) and (2) are reacted in presence of an effective amount of a polymerization inhibitor and / or lack of oxygen.
