Abstract:
A lubricant composition with a comb polymer and a synthetic base oil has improved viscosity characteristics at low operating temperatures. In addition, a comb polymer can be used for producing a lubricant having an R-factor of less than or equal to 8, wherein the R-factor is defined as the ratio of the kinematic viscosity at −20° C. and the kinematic viscosity at +20° C.

Claim (Index 16):
The method use according to  claim 10 , wherein the comb polymer (B) comprises:\n (a) 25 to 30% by weight of esters of (meth)acrylic acid and a hydroxylated hydrogenated polybutadiene, (b) 0.2 to 15% by weight of styrene, (c) 0.2 to 15% by weight of alkyl methacrylates comprising 12 to 14 carbon atoms in the alkyl chain, (d) 50 to 65% by weight of butylmethacrylate, and (e) 0.1 to 0.2% by weight of methylmethacrylate, based on the total weight of the comb polymer.
