Abstract
Poliesteri a rapida velocità di cristallizzazione ottenuti dalla policondensazione di acido tereftalico con almeno un glicol alchilenico C2- C4 in presenza di 0,1-1,5% 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.
