Abstract (en)
[origin: WO2019063945A1] 1) A hydrocarbon copolymer comprising two end groups preceded by an ester function, and selected from a 2-oxo-1,3-dioxolan-4-yl (or cyclocarbonate), a dithiocyclocarbonate, an exo-vinylene cyclocarbonate, or a 2-oxo-1,3-dioxolen-4-yl, the main chain of which comprises units (I) and (II) where R °, in particular, is the methyl radical; and the number average molecular weight Mn of which is between 400 and 100,000 g/mol; 2) a method for producing the aforementioned copolymer, comprising: (i) a step of heating a statistical bipolymer A selected from a poly(butadiene-isoprene), a poly(butadiene-myrcene) and a poly(butadiene-farnesene); followed by (ii) a step of heating the resulting product in the presence of a chain transfer agent; and 3) a use as an adhesive, in a mixture with an amino-functional compound having at least two amino groups.
