Low color polyisobutylene succinic anhydride-derived emulsifiers

A composition comprising:

• a) a reaction product from the reaction of a polyolefin polymer having at least 20 carbon atoms with maleic anhydride and/or maleic acid forming a succinic anhydride functionalized polyolefin,
• b) further reacting said functionalized polyolefin with a polyol, alkanolamine, amine, or ammonia or another base, or combinations thereof, and
• c) optionally diluting with a diluent oil,
• wherein said reaction product of steps “a” and “b” has a color on the Garner Color scale of equal to or less than 2.

A process for making a low color polyisobutylene succinic anhydride or surfactant therefrom from reacting a polyolefin with maleic anhydride, maleic acid, fumaric acid, or their esters comprising:

• reacting a polyolefin having at least 20 carbon atoms and at least one carbon-to-carbon double bond with maleic anhydride in its anhydride or acid form or fumaric acid or the esters of maleic or fumaric acid in a molar ratio of total maleic anhydride, maleic acid, fumaric acid and their esters to polyolefin of less than 1.3 to 1;
• optionally further reacted with a polyol, alkanolamine, amine, or ammonia or another base, or combinations thereof;
• and
• optionally diluted with a diluent oil;
• and wherein the color of the resulting reaction product is equal to or less than 2 on the Gardner Color scale.
