Abstract

Inventia se refera la un procedeu de obtinere a unei folii sintetice cu stabilitate termica înalta dintr-o solutie de polimer cu structura de acid poliamidic obtinut prin policondensarea dianhidridei pirometrice cu 4,4'-diaminodifenileterul sau amestecul acestuia cu 4,4'-diaminodifenilmetanul într-un solvent amidic dipolar, prin depunerea acestei solutii în straturi succesive subtiri pe o banda - suport antiaderenta, formata din hârtie celulozica siliconizata sau aluminizata, urmata de uscare si tratament termic la temperatura înalta. Folia poliimidica obtinuta prezinta foarte bune proprietati electroizolante si o înalta stabilitate termica, procesul de degradare termooxidativa, începând abia la 440 ... 450 degree C.
