Polyolefin substituted carboxylic acylating agents having reduced chlorine content of less than 2,000 ppm and a degree of succination of 1.1-2 have been made from polyisobutylene, chlorine and maleic anhydride. The acylating agents are further reacted with amines and/or alcohols to form dispersants having reduced chlorine content
Divulgation d'agents d'acylation à base de composés carboxyliques substitués par des polyoléfines ayant une teneur réduite en chlore, inférieure à 2 000 ppm, et un degré de succination allant de 1,1 à 2. Ces agents ont été produits à partir de polyisobutylène, de chlore et d'anhydride maléique. On les fait ensuite réagir avec des amines et/ou des alcools pour former des dispersants à teneur réduite en chlore.
