Abstract (en)
[origin: EP0744457A2] Lubricating oil additive contains an amt. of graft polymers with a VI improving action. The graft polymers (PFP) are made up of polyalkylmethacrylate macromonomers (A) in amts. of 10-90 wt.%, which are copolymerised with alkyl(meth)acrylic acid esters (AMA) contg. 6-30C alkyls in amt. of 0-90 wt.% and with non-functionalised comonomers (B) chosen from alkyl(meth)acrylic acid esters contg. 1-5C alkyls, styrene, alkylstyrenes contg. 1-4C alkyls, and 2-12C fatty acid vinyl esters in amts. of 0-60 wt.%, and also with functionalised comonomers (C) chosen from functionalised (meth)acrylic acid esters and amides and vinyl heterocycles in amts. of 0-40 wt.%. The sum of the copolymerised monomers is 10-90 wt.% in a carrier medium (TM). The graft polymers are also claimed.
