| titleOfInvention |
Composition containing a block copolymer and a method of lubricating an internal combustion engine |
| abstract |
The present invention provides lubricating compositions containing oils and block copolymers of lubricating viscosity. The block copolymers (a) C 1 -30 alkyl (meth) acrylate unit, but the hold, at least 50wt% of the C 1 -30 alkyl (meth) acrylate unit is C 12 -15-alkyl (meth) acrylate units, C 1 -30 alkyl (meth) acrylate unit of 50wt% or less C 16 -20-alkyl (meth) acrylate unit and, with the proviso that C 1 -30 alkyl (meth) the total number of at least 8, the hydrophobicity of the alkyl acrylate unit group mean the carbon atoms 1 block; And (b) a second block having a (meth) acrylic unit further bearing a heteroatom-containing group which provides a polar group. The present invention also relates to a method for lubrication of an internal combustion engine by lubrication of the engine with the lubricating composition. The present invention also relates to the use of said block copolymers for use as emulsifiers and / or pour point depressants. |
