Low chlorine content compositions for use in lubricants and fuels

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...

Summary: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.
