Abstract
Preparazione di resine poliestere ad elevato peso molecolare a partire da resine con viscosità intrinseca I.V. inferiore a 0,57 dl/g comprendente le operazioni di:1) miscelazione del polimero allo stato fuso con un additivo di poliaddizione contenente almeno due gruppi capaci di reazioni di addizione con i gruppi OH e COOH terminali del poliestere;2) trasformazione del poliestere fuso in particelle solide e successivo trattamento di cristallizzazione delle stesse;3) riscaldamento delle particelle a temperature tra 150° e 210°C fino ad ottenere l'aumento desiderato della viscosità intrinseca.
