Definitions
- the present invention relates to lubricating compositions having improved cold properties. More particularly, the present application relates to the use of a specific polymer to improve the cold thickening properties of a lubricating composition.
- Another object of the present invention is to provide a lubricating composition having good cold thickening properties.
- R4 groups represent, independently, a C2-C4 alkylene group
- m is an integer ranging from 0 to 4, more preferably from 0 to 2.
- each A can be the same or different, and the fragments (AO) m can be linked randomly or in blocks.
- the hydrocarbon-based polymer may also contain at least one structural unit distinct from the isobutylene or 1,2-butylene units.
- the hydrocarbon polymer may for example comprise one or more of the following units:
- this double bond can be partially or totally hydrogenated by hydrogenation.
- the total number of butylene units (isobutylene and/or 1,2 butylene), relative to the total number of structural units of the hydrocarbon polymer, can be determined by analyzing the hydrocarbon polymer by 13 C nuclear magnetic resonance spectroscopy and using the following equation:
- the number-average molecular weight (Mn) of each of the (co)polymers (Y) is preferably from 1,000 to 25,000 g. mol -1 , more preferably from 2,000 to 20,000 g. mol -1 , particularly preferably from 3,000 to 15,000 g. mol -1 , more preferably from 4,000 to 10,000 g. mol -1 .
