Zusammenfassung:Method for modifying ethylene polyterephthalate or butylene polyterephthalate characterized in that per 100 parts by weight of ethylene polyterephthalate or butylene polyterephthalate thermoplastic copolyesterethers are used whose hardness ranges from 35 to 65 ShD, preferably from 40 to 60 ShD, and whose limiting viscosity number is higher than 0.7, in an amount between 2 and 30 parts by weight.
