Patent

CA 2589358

This invention relates to a process for preparing an additive comprising the steps of: (1) reacting a polymer derived from of an olefin containing 2 to 8 carbon atoms with an acylating agent to form an acylated polymer; and (2) reacting the acylated polymer of step (1) in a medium substantially free of to free of sulphur with: (a) ammonia or an amine to form a succinimide product; or (b) water to form a hydrolysed product, wherein the mole ratio of the acylating agent to polymer in step (1) is from 0.3:1 to 1.6:1. The invention further relates to compositions containing the additive and its use.

L'invention concerne un procédé de préparation d'un additif qui comprend les étapes consistant : (1) à mettre en réaction un polymère dérivé d'une oléfine contenant 2 à 8 atomes de carbone avec un agent d'acylation afin de former un polymère acylé; (2) à mettre en réaction le polymère acylé de l'étape (1) dans un milieu sensiblement ou totalement dépourvu de soufre avec : (a) de l'ammonium ou une amine en vue de former un produit succinimide ; ou (b) de l'eau en vue de former un produit hydraulisé dont le rapport molaire agent d'acylation-polymère de l'étape (1) est compris entre 0.3:1 et 1.6:1. L'invention concerne, en outre, des compositions contenant cet additif et son utilisation.
