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

A method for producing a propulsion nozzle, wherein the nozzle is produced from an ablative resin, the method including a step of pre-polymerization wherein an innovative aldehyde compound is used.

Method for producing an ablative resin

A method for producing an ablative resin by carrying out a reduction reaction for the reduction of a compound of formula A, followed by a polymerization reaction, formula A being the following: 

The present application relates to a method for preparing epoxy resins from a mixture of epoxidized phenolic compounds, wherein said epoxidized phenolic compounds are obtained by the epoxidation of natural phenolic compounds selected from the group comprising simple phenol, acid-phenol, coumarin, naphthoquinone, stillbenoid, flavonoid, isoflavanoid, anthocyanin, condensed tannin and hydrolyzable tannin.

Methods for producing thermosetting epoxy resins

The invention relates to a method for functionalizing natural fatty substances: According to said method, plant oils including at least two unsaturations and the derivatives thereof, fatty acids including at least one unsaturated compound and the derivatives thereof, and mixtures of same, are reacted with a thiol derivative of formula (I), at a temperature of between 0&#xb0; C. and the temperature of total degradation of the natural fatty substance and in the presence of a thermal initiator compound or a redox initiator, or by UV radiation, or by UV radiation and in the presence of a photoinitiator. The invention also relates to the resulting functionalized fatty substances and to the use thereof for the preparation of polymers. The invention further relates to a method for preparing polymers from at least one functionalized fatty substance obtained by said functionalization method.

Method for functionalizing natural fatty substances

A method for preparing a formaldehyde-free phenolic plastic resin, includes a step of preparing a hardener via careful oxidation of a polyol and a step of reacting the hardener with phenolic compounds.

Resins of the phenoplast type obtained from phenolic compounds and from macromolecular hardeners bearing aldehyde functions
