1) hydrocarbon copolymer comprising 2 end groups preceded by an ether function and chosen from a 2-oxo-1,3-dioxolan-4-yl (or cyclocarbonate), a dithiocyclocarbonate, a 2-oxo-1,3-dioxolen-4 -yl, whose main chain comprises the units (I) and (II) where R0 is in particular the methyl radical; and whose number-average molecular weight Mn is between 400 and 100000 g / mol. 2) A process for preparing said copolymer comprising: (i) a step of heating a random bipolymer A selected from poly (butadiene-isoprene), poly (butadiene-myrcene) and poly (butadiene-farnesene); and then (ii) a step of heating the product formed, in the presence of a chain transfer agent. 3) Use as an adhesive, in admixture with an amine compound comprising at least two amine groups. |
