Abstract:
The present invention relates to semiaromatic and semicrystalline thermoplastic polyimides obtained by polymerization of at least one aromatic compound comprising two anhydride functions and/or carboxylic acid and/or ester derivatives thereof and a diamine comprising between 13 and 22 carbon atoms. These polyimides may be converted into plastic articles by various methods, such as injection-molding.
