Abstract
Procedimento per la poliaddizione allo stato solido di una resina poliestere in cui la resina viene miscelata allo stato fuso con una dianidride di un acido aromatico tetracarbossilico e poi granulata ed i granuli vengono sottoposti a cristallizzazione e successivamente a trattamento di rigrado della resina, caratterizzato dal fatto che la temperatura di rigrado è superiore alla TG della resina ma inferiore a 170°C, ed è compresa preferibilmente tra i 130° e 170°C.
