POLYIMIDE MOLDING

摘要

The invention provides polyimide fiber and film with high strength, high modulus and high crystallinity from a new polyimide with good moldability, which is believed to be capable of melt molding without detriment to the high crystallinity, said polyimide comprising repeating structural units of formula (I) wherein at least 85 mole % comprise repeating units of formula (II) and 0.5 to 15 mole % comprise repeating units of formulae (III), (IV) and/or (V) except for formula (II).
