Abstract

Composizioni poliestere ad elevata viscosità del fuso ottenute per reazione ad alta temperatura di una resina poliestere, previamente essiccata, con almeno una anidride policarbossilica e con almeno un composto di formula generale (I): (FORMULA I) dove X rappresenta un radicale organico divalente tale da dare origine a eterocicli scelto fra quelli di formula -CR1R2-CR3R4- ovvero -CR1R2-CR3R4-CR5R6-, con R1, R2, R3, R4, R5 e R6, uguali o differenti tra loro, che rappresentano un atomo di idrogeno od un metile; n vale zero oppure 1; Z rappresenta un radicale bivalente alifatico, lineare o ramificato, o ciclico contenente un numero di atomi di carbonio compreso tra 1 e 16 ed eventualmente eteroatomi quali ossigeno, zolfo o azoto, oppure Z rappresenta un radicale aromatico a alchilaromatico contenente da 6 a 20 atomi di carbonio.
