摘要
The invention relates to a biosourced polymer obtained by dual chemical functionalization of chitosan, usable for catalytic carbonation of cyclic ethers by means of carbon dioxide, and a binder composition for creating layers and/or coatings for road construction and/or civil engineering, marking materials, or sealing or insulation materials. Said composition contains a polyhydroxyurethane polymer binder resulting from the reaction of at least one polyamine with at least one polycyclocarbonate. Said polycyclocarbonate was obtained by carbonating a (cyclic) poly(ether) with carbon dioxide catalyzed by said biosourced polymer.
