Abstract
Two groups of thermotropic poly(ester-imide)s were prepared from trimellitic anhydride (TMA) and various bisphenols. The first group contains α, w-di- amines the second group w-amino acids as flexible spacers. Both groups possess a layered supermolecular structure in the solid state and form a smectic melt above the melting points. The poly(ester-imide)s with diamine spacers possess a regular primary structure, they crystallize rapidly and reach a high degree of crystallinity. Furthermore, they show unusually high heat distortion temperatures (HDTs) which are directly related to their melting points.Keywords
