CA 2359951

A process is provided for preparing a mixture of (1) a copolymer of a polyalkene and an unsaturated acidic reagent and (2) a polyakenyl derivative of an unsaturated acidic reagent, said process comprising (a) copolymerizing (1) a polyalkene containing alkylvinylidene isomer and non-alkylvinylidene isomers and (2) an unsaturated acidic reagent under polymerization conditions in the presence of a free radical initiator; and (b) reacting the product of step (a) with an unsaturated acidic reagent at elevated temperature in the presence of a strong acid. The product of the process can be used to make polysuccinimides that are useful in lubricating oil compositions.

L'invention concerne un procédé de préparation d'un mélange (1) d'un copolymère d'un polykalcène et d'un réactif acide insaturé et (2) d'un dérivé polyalcénylique d'un réactif acide insaturé. Ledit procédé consiste à : (a) copolymériser (1) un polyalcène contenant un isomère alkylvinylidène et des isomères non-alkylvinylidènes et (2) un réactif acide insaturé, dans des conditions de polymérisation, en présence d'un amorceur radicalaire ; et (b) faire réagir le produit de l'étape (a) avec un réactif acide insaturé, à une température élevée, en présence d'un acide fort. Le produit du procédé peut être utilisé pour la fabrication de polysuccinimides utiles dans des compositions d'huiles de lubrification.
