Provided is a method making it possible to ensure a gradual release of polymer chains within a liquid medium, the method comprising bringing the liquid medium into contact with specific solid objects formed by polymer chains soluble in the medium and carrying hydrophobic side groups ensuring physical crosslinking between the polymer chains within the solid objects. The released chains may in particular be used as inhibitors of the formation of inorganic or organic deposits (scale inhibitors) within a liquid medium, typically in the field of oil extraction.

A method for replacing glycol-based mutual solvents in an oil field application comprising: obtaining an alternative solvent and solvent blends and replacing all or a portion a glycol-based mutual solvent, which forms a component of an oil field formulation, with the alternative solvent or solvent blends, wherein the oil field formulation can be utilized in an oil field application.

Use of environmentally friendly solvents to replace glycol-based solvents

The invention relates to compositions for inhibiting the formation of deposits in underground formations such as oil wells, comprising, in a solvent medium, polymers P resulting from the radical copolymerization, preferably controlled and in solution, of a mixture including: monomers having an ethylenically unsaturated structure, selected from monomers that form, by polymerization, a polymer that has an effect of inhibiting the formation of organic and/or inorganic deposits; and polyethylenically unsaturated, cross-linking monomers carrying at least one group that can be cleaved between two ethylene unsaturations, said polymers P being present in the solvent in the form of dispersed nanogels.

Composite core/sheath particulates comprising an organic polymer core at least partly coated with calcium carbonate, these core/sheath particulates having a mean particle size not exceeding 5 .mu.m, well suited for reinforcing plastic/elastomer substrates, are conveniently converted, e.g., via calcination, into hollow calcium carbonate microbeads which comprise CaCO.sub.3 shells having a mean particle size not exceeding 5 .mu.m; such hollow microbeads are themselves well suited for enhancing the low-temperature flexibility of elastomer substrates, notably vehicle tires.
