1. A hydrocarbon-based polymer bearing an alkoxysilane end group, said hydrocarbon-based polymer being of formula (1): in which: each carbon-carbon bond of the chain noted as is a double bond or a single bond, in accordance with the valency rules of organic chemistry; the groups R1, R2, R3, R4, R5 and R6 are each, independently of the other groups or otherwise, a hydrogen, a halo group, an alkoxycarbonyl group or an alkyl group, the groups to R1 to R6 possibly being linked together as members of the same saturated or unsaturated ring or heterocycle (i.e. comprising at least one carbon-carbon double bond, including aromatic rings), m and p are integers each within a range from 0 to 5, the sum m+p itself being within a range from 0 to 10, R and R′, which may be identical or different, each represent a linear or branched, alkyl group comprising from 1 to 4 carbon atoms, Z is a divalent group chosen from alkylene groups, optionally interrupted with an ester function, and comprising from 1 to 22 carbon atoms, q is an integer equal to 0 or 1, r is an integer equal to 0, 1 or 2, and n is an integer such that the number-average molar mass Mn of the hydrocarbon-based polymer of formula (1) is within a range from 400 to 50 000 g/mol, and the polydispersity index (PDI) of the hydrocarbon-based polymer of formula (1) is within a range from 1.0 to 2.0. |
