Abstract

L'invenzione si riferisce ad un processo di (co) polimerizzazione in sospensione per la preparazione di fluoropolimeri termoplastici contenenti idrogeno, quali ad esempio i copolimeri etilene/clorotrifluoroetilene od etileneltetra-fluoroetilene, oppure gli omopolimeri o copolimerl del vinilidenfluoruro, in cui si impiega come iniziatore di polimerizzazione il bis-diclorofluoroacetil perossido (CFCl2-CO-O)2 (DCFAP). Da tale processo si ottengono prodotti dotati di elevata stabilità termica, significativamente maggiore di quella ottenibile utilizzando il bis-tricloroacetilperossido (TCAP).
