Abstract
Thermoplastic polyester compositions comprising polyester resin modified by introducing perfluoropolyether blocks in the polymeric chain characterized by high crystallization rate of the melted mass and therefore by an improved processability. In particular the use of such compositions in a process for preparing molded thermoplastic articles allows working at lower temperatures of the mold and with shorter molding times. Process for preparing modified resins.
