Abstract
Poliesteri dell'acido 2,6-naftalenedicarbossilico aventi ridotta velocità di cristallizzazione ottenute dalla policondensazione di:a) almeno un diolo costituito essenzialmente da un glicole alchilenico C2-C4 ;b) un diacido costituito essenzialmente dall'acido 2,6-naftalenedicarbossilico, eventualmente sostituito con alogeni o con radicali alchilici C1-C4, od un suo derivato;c) 0,1-5% in moli, rispetto alla somma totale dei componenti acidi, di almeno un polialchilenglicole diidrossi terminato avente peso molecolare medio compreso tra 500 e 5000.
