Thermotropic aromatic polyester-imides having improved heat distortion resistance, process for their preparation, and their use for the production of mouldings, filaments, fibres and films

摘要

Thermotropic polyester-imides which contain the radicals of C8-C16-alkylene- alpha , omega -bistrimellitimides can be processed thermoplastically without difficulty in spite of their high heat distortion resistance.
