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 6g, and have been subjected to a phenol/aldehyde treatment process, to increase the intrinsic viscosity by at least 4%
compared with standard materials.
