Abstract

Procedimento per il regrado allo stato solido di resine poliestere mediante reazione di poliaddizione caratterizzato dal fatto che la resina viene regradata in presenza di un additivo di regrado costituito da un composto bifunzionale differente dalle dianidridi degli acidi aromatici, contenente due gruppi capaci di reazioni di addizione per apertura di anello con i gruppi terminali del poliestere, scelto esemplificativamente tra le dianidridi degli acidi tetracarbossilici alifatici e cicloalifatici.
