ABSTRACT:
A method of stabilization of a melt viscosity of aliphatic- and/or aromatic homo- and/or co-polyesters containing catalysts and/or initiators, involves adding a masking agent which is tropon, .alpha.-tropolon, thujaplicin, pupurogallin or mixtures thereof to a melt resulting during synthesis of polyesters or during regeneration of polyesters.
