Abstract:
A comb polymer can be used for reducing a Noack evaporation loss of a lubricant composition, especially of an engine oil composition. Application of the comb polymer to the lubricant composition can bring about the desired reduction. The comb polymer can include specified amounts of macromonomer and alkyl acrylates. Resulting lubricant compositions can include the comb polymer.

Claim (Index 8):
An additive composition, comprising:\n (A) 60 to 80% by weight of a base oil, and (B) 20 to 40% by weight of a polyalkyl(meth)acrylate based comb polymer, comprising the following monomers:\n (a) 10 to 25% by weight of at least one ester of (meth)acrylic acid and a hydroxylated hydrogenated polyhutadiene; and \n (b) 0.5% to 11% by weight of at least one C 4-18  alkyl acrylate.
