Abstract

1) Hydrocarbon-based copolymer comprising two end groups preceded by an ether function and chosen from a 2-oxo-1,3-dioxolan-4-yl (or cyclocarbonate), a dithiocyclocarbonate, and a 2-oxo-1,3-dioxolen-4-yl, the main chain of which comprises units (I) and (II) 2) Process for preparing said copolymer, comprising: 3) Use as adhesive, as a mixture with an amine compound comprising at least two amine groups.
