A method for the preparation of magnetic fluorescent nanobeads, comprising and an amphiphilic polymer shell and a core having magnetic properties; said nanobeads comprise a core having superparamagnetic behaviour, including an aggregate of ferromagnetic or ferromagnetic nanoparticles and comprising the steps of:
a) providing colloidal nanoparticles, covered by a surfactant, said nanoparticles having such size as to show superparamagnetic properties at room-temperature (or anyhow at the temperature of nanobeads use);
b) adding a solution of amphiphylic polymer to a solution of said particles in a solvent to obtain a mixture of said superparamagnetic nanoparticles and polymer;
c) adding a solvent wherein said nanoparticles arc insoluble and the used polymer is only partially soluble to the mixture obtained in b).

The present invention relates to a copolymer comprising units derived from monomers (i) an α-olefin and (ii) an ethylenically unsaturated carboxylic acid or derivatives thereof esterified with a primary alcohol branched at the β- or higher position, wherein the copolymer has a reduced specific viscosity of up to 0.08. The invention further provides for a lubricating composition containing said copolymer. The invention further provides a method and use of controlling viscosity index by supplying to an oil of lubricating viscosity the copolymer with pendant groups. In addition, the copolymer of the present invention may be useful as a base oil replacement.
