Abstract:
1. A modified polyamide comprising a polyamide modified by a compound comprising at least one aromatic hydroxyl group chemically bonded to the chain of the polymer, wherein the polyamide is produced by polymerization starting from at least the following monomers: i) A1) a difunctional hydroxyaromatic compound comprising two functional groups, wherein the two functional groups can react with an amine functional group, and wherein the compound A1) is a compound of following formula (I): in which Z is a polyvalent, at least trivalent, aromatic or arylaliphatic hydrocarbon radical and x is between 1 and 10; and ii) at least one polyamide monomer selected from the group consisting of: where when the monomer B is solely of the B1) type, the molar proportion of monomer A1) with respect to the monomers A1) and B) is between 0.1% and 30%.
