The invention relates to polymeric-inorganic nanoparticle compositions and preparation processes thereof. The invention also relates to an additive and lubricant compositions comprising these polymeric-inorganic nanoparticle compositions, as well as to the use of these polymeric-inorganic nanoparticle compositions in an oil lubricant formulation to improve tribological performance, in particular to improve extreme pressure performance and friction reduction on metal parts.

Polymeric-inorganic nanoparticle compositions, manufacturing process thereof and their use as lubricant additives

The present application relates to compositions comprising at least one polyalkyl(meth)acrylate polymer, a graft copolymer comprising a copolymer based on ethylene as graft base and one or more polyalkyl(meth)acrylate polymer(s) grafted thereon, and at least one non-grafted ethylene-based copolymer, as well as to the use of such compositions to improve the performance, especially the cold flow properties and injector nozzle coking tendency of middle distillates, especially diesel fuels, biodiesel and blends thereof.

Cold flow improver with broad applicability in mineral diesel, biodiesel and blends thereof

The present invention describes a composition comprising at least one polyalkyl(meth)acrylate polymer having a number average molecular weight Mn of from 1000 to 10000 g/mol and a polydispersity Mw/Mn of from 1 to 8 and at least one ethylene vinyl acetate copolymer comprising units being derived from at least one alkyl (meth)acrylate having 1 to 30 carbon atoms in the alkyl residue. The composition is useful as cold flow improver in fossil fuel oil and or biodiesel fuel oil.

Composition to improve cold flow properties of fuel oils

The present invention describes a composition comprising at least one antioxidant and at least one ethylene vinyl acetate copolymer comprising units being derived from at least one alkyl (meth)acrylate having 1 to 30 carbon atoms in the alkyl residue. The composition is useful as cold flow improver and oxidation stabilizer in fossil fuel oil and or biodiesel fuel oil.
