Abstract

Poliesteri a bassa velocità di cristallizzazione ottenuti dalla policondensazione di acido 2,6-naftalendicarbossilico con almeno un glicol (ciclo) alchilenico C2-C10 in presenza di 0,5-50% in moli di un reagente copolimerizzabile di formula generale:ROOC-Ar-OOC-Ar'-COO-Ar-COOR (I)dove Ar e Ar' rappresentano radicali aromatici e R rappresenta un alogeno, un atomo di idrogeno o un radicale alchilico C1-C4.
