Abstract
The present invention relates to a succinic diester polymer which is used in the preparation of water-in-oil macroemulsions. Said polymer, which has an excellent ability to stabilize a water-in-oil macroemulsion, has the formula (I) wherein L is a polyalkenyl group having a number average molecular weight of are poly(alkyleneoxy) chains with a molecular weight of from 500 to 1,200, where each alkyleneoxy group contains 2 or 3 carbon atoms and the number of alkyleneoxy groups being ethyleneoxy groups is at least 50% of the total number of alkyleneoxy groups, and R1 and R2 independently are alkyl groups having of from 1 to 3 carbons atoms. The emulsions of the invention can be used as a diesel fuel, a gasoline fuel, a heating fuel, a dry cleaning liquid, a metalworking fluid or a personal care formulation.
