Abstract

The present invention relates to a polymeric material from the family of polyamides characterised in that said polyamides have an amine end group concentration of at least 60 equivalents/10<6>g, and have been subjected to a phenol/aldehyde treatment process, to increase the intrinsic viscosity by at least 4% compared with standard materials.
