A process for manufacturing a polybenzoxazine monomer, crosslinking the latter, and using the crosslinked product to form an ablative thermal protection system for a thruster nozzle or atmospheric reentry body.

Process for producing a polybenzoxazine monomer

Process for the production of a polybenzoxazine monomer

A process for manufacturing a cross-linked product has improved charring and thermal stability properties in which there is cross-linking of a benzoxazine monomer.

Process for manufacturing a cross-linked product

Disclosed is a biosourced polymer obtained by dual chemical functionalization of chitosan, usable for catalytic carbonation of cyclic ethers by 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. The composition contains a polyhydroxyurethane polymer binder resulting from the reaction of at least one polyamine with at least one polycyclocarbonate. The polycyclocarbonate was obtained by carbonating a (cyclic) poly(ether) with carbon dioxide catalyzed by the biosourced polymer.

Biosourced polymer for manufacturing, via catalytic carbonation, a non-bituminous polyhydroxyurethane binder for roadway or civil engineering-related uses
