Abstract
Fast crystallizing polyester compositions obtained by reacting a polyester having an intrinsic viscosity of greater than 0.3 which polyester comprises aromatic or cycloaliphatic residues obtained from diacids and/or hydroxyacids and aliphatic, aromatic or cycloaliphatic residues of diols with an ionizable metal salt of a compound containing a group of the formula >NH, preferably selected from compounds of the formula: ##STR1## and acid amides, lactams, polyamides and sulphonamides.
