Abstract

Una poliestereimmide termotropica, con struttura nematica della fase liquido-cristallina in un intervallo utile di temperatura, è costituita da unità di formula (FORMULA) con il seguente rapporto tra le unità a/ (b+c) =1c/b = da 0 a 50/50, preferibilmente c/b < 30/70.La poliestereimmide della presente invenzione è un materiale con caratteristiche autorinforzanti o di rinforzo di materiali termoplastici tradizionali.
