ABSTRACT:
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.
