1) Hydrocarbon-based copolymer comprising two end groups preceded by an ester function and chosen from a 2-oxo-1,3-dioxolan-4-yl (or cyclocarbonate), a dithiocyclocarbonate, an exo-vinylene cyclocarbonate and a 2-oxo-1,3-dioxolen-4-yl, the main chain of which comprises units (I) and (II) ##STR00001## in which R.sup.0 is notably a methyl radical; and the number-average molecular mass Mn of which is between 400 and 100 000 g/mol. 2) Process for preparing said copolymer, comprising: (i) a step of heating a statistical bipolymer A chosen from a poly(butadiene-isoprene), a poly(butadiene-myrcene) and a poly(butadiene-farnesene); and then (ii) a step of heating the product formed, in the presence of a chain-transfer agent. 3) Use as adhesive, as a mixture with an amine compound comprising at least two amine groups.

The invention relates to a two-component composition comprising: a part A comprising a complex of organoborane with an amine; a part B comprising a polymer comprising at least one acrylic group and at least one isocyanate group;

the composition comprising at least one acrylic monomer or oligomer in part A and/or in part B of the composition.

The invention also relates to the use of said composition as an adhesive for binding two substrates together.

A nail tip curing composition includes an Extend Gel, an edge-off flat brush, a nail filing device, a plurality of GEL-X tips, a pH Bonder, and a Non-Acidic Gel Primer. The pH Bonder forms a pH Bonder layer on a surface of a fingernail. The Non-Acidic Gel Primer forms a Non-Acidic Gel Prime layer overlapped on the pH Bonder layer. The Extend Gel forms an Extend Gel layer overlapped on the Non-Acidic Gel Prime layer. The GEL-X tip is filed by the nail filing device and the Extend Gel is applied on an underside contact surface of the Gel-X tip by the edge-off flat brush. The underside contact surface of the Gel-X tip is contacted with the Extend Gel layer on the fingernail in such a manner that the Gel-X tip is firmly affixed on the fingernail.
