Abstract: Mineral lubricating oil compositions which contain a predominant proportion of a mineral lubricating oil together with a pour point depressant based on alkyl acrylate or alkyl methacrylate polymers and a viscosity index (VI) improver comprising a special selectively hydrogenated copolymer of styrene and a conjugated diene. The VI improver employed is a selectively hydrogenated, random butadiene-styrene copolymer containing from 35 to 45% by weight of styrene and possessing a particular structure and distribution of the monomers. The compositions exhibit high stability to shear and may therefore in particular be used for lubricating I.C. engines or gearboxes.

Abstract: The invention relates to a thermoplastic moulding composition comprising A) a (co)polymer in a proportion of from 40 to 99 % by weight, based on A) and B), which contains at least 50 % by weight, based on A), of a copolymerised vinylaromatic monomer, and B) a soft component in a proportion of from 1 to 60 % by weight, based on A) and B), which comprises a graft base and a graft shell, where the graft base is built up from, in each case based on the graft base, b1) from 40 to 99.5 parts by weight of ethylene, b2) from 0.5 to 30 parts by weight of an acrylate of tricyclodecenyl alcohol and b3) from 0 to 50 parts by weight of at least one ethylene-copolymerisable monomer, and where the graft shell is built up from at least one monomer from the group consisting of vinylaromatic and ethylenically unsaturated monomers. The moulding composition may contain conventional additives and is used to produce mouldings.
