Abstract
The presently claimed invention is directed to novel polyesters which are obtainable by reacting a mixture comprising at least one C8-C20 Guerbet alcohol, at least one aliphatic or cycloaliphatic dicarboxylic acid and at least one polyol with a hydroxyl functionality in the range of ≥2 to ≤6 and the use of these polyesters as a component of lubricating oil compositions.
Claims17
A polyester which is obtainable by reacting a mixture comprising
- a) at least one acid selected from the group consisting of aliphatic dicarboxylic acids having 5 to 20 carbon atoms and cycloaliphatic dicarboxylic acid having 4 to 36 carbon atoms,
- b) at least one monoalcohol of the formula I,
- wherein p is 2;
- and
- c) at least one polyol with a hydroxyl functional in the range of ≥2 to ≤6 and wherein
- ≥25 to ≤50% by weight of component a),
- ≥40 to ≤70% by weight of component b) and
- ≥0.1 to ≤20% by weight of component c),
- whereby and the sum of the weight of all components a), b) and c) adds up to 100%.
