TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The lubricant contains: a polyalphaolefin having a kinematic viscosity of 3-10 mm2/second, measured at 100 degrees C in accordance with ASTM D 445; at least one solidifying point improver and at least one mineral oil of the group III having a kinematic viscosity of 3-10 mm2/second, measured at 100 degrees C in accordance with ASTM D 445. The lubricant has a kinematic viscosity of at least 30 mm2/second, measured at 100 degrees C in accordance with ASTM D 445. Preferred Components: The polyalkyl(meth)acrylate has a weight average molecular weight of 5000-15000 g/mole and polydispersity of 1.4-1.9. (II) contain a mixture of branched and linear groups, in which: the weight ratio of branched to linear groups of R2 is 60:40-20:80; and at least 50 wt.% of repeat units of (II) having a branched radical of R2 has a branching at the second position, where the mixture contains repeating units with methyl branching and ethyl branching or with methyl branching and long chain branching. (II) contains a mixture of radicals of R2 having different number of carbon atoms, in which the amount of the residues of R2 having 12-15C is greater than the amount of the residues of R2 having 7-11C. The repeating units of the polyalkyl(meth)acrylate are derived from the dispersed monomers. In (II), the weight fraction of linear radicals of R2 with 9-11 or 12-15C is higher than the weight fraction of the branched radicals of R2 with 9-11C or 12-15C. The polymerizable composition contains 2-4.5 wt.% of chain transfer agents. Preferred Process: The polymerization is carried out using at least one, preferably at least two chain transfer agents. In the process: at least 60 wt.% of the monomers are added; the initiator is added in at least two steps, where the initiator added in the first step is less than in the subsequent steps; and the amount of the solvent added during the polymerization is 0.5-10 wt.%. The polymerization is carried out at 0-30 degrees C above the temperature of the initiator, with which the half life of the initiator is 30 minutes. EXAMPLE - No suitable example given.
