1. A process for manufacturing a cross-linked product comprising the cross-linking of a benzoxazine monomer of formula A provided below:
in this formula:
A1 is selected from: (i) saturated, unsaturated or aromatic, monocyclic or polycyclic carbocyclic or heterocyclic groups, substituted by a cross-linkable group, (ii) saturated or unsaturated, linear or branched hydrocarbon chains, optionally interrupted by one or more heteroatoms, substituted by a cross-linkable group, in the alternative (i) or (ii), said cross-linkable group is selected from: a hydroxyl group, an amine group, a maleimide group, an acetylene group, an allyl group, a carbonitrile group, a phthalimide group, a phthalonitrile group, an epoxy group,
R1a is selected from: substituted or unsubstituted furfuryl groups, saturated, unsaturated or aromatic, monocyclic or polycyclic, substituted or unsubstituted carbocyclic or heterocyclic groups, substituted or unsubstituted aralkyl groups, linear or branched, saturated or unsaturated, substituted or unsubstituted hydrocarbon chains, optionally interrupted by one or more heteroatoms,
na is an integer comprised between 0 and 2,
R2a is selected from: electron-withdrawing groups, saturated or unsaturated, substituted or unsubstituted, linear or branched hydrocarbon chains comprising between 1 and 6 carbon atoms, optionally interrupted by one or more heteroatoms, saturated, unsaturated or aromatic, substituted or unsubstituted carbocyclic or heterocyclic groups.
