Methods are revealed for producing polyolefin substituted carboxylic acylating agents having less than 1000 ppm chlorine, and reaction products formed therefrom such as dispersants. The carboxylic acylating agents are formed by reacting a polyolefin having labile halogen content with an .alpha.-.beta. unsaturated carboxylic acid. The products formed in this invention are used in lubricating compositions.
L'invention porte sur des méthodes pour obtenir des dérivés de substitution polyoléfiniques d'agents d'acylation carboxyliques, renfermant moins de 1000 ppm de chlore; produits de réaction ainsi formés, notamment des dispersants. Les agents d'acylation carboxyliques sont formés par réaction d'une polyoléfine renfermant un halogène instable avec un acide carboxylique insaturé en alpha,bêta. Les produits obtenus grâce à l'invention servent dans des compositions lubrifiantes.
