Abstract:
1. Melt processable copolymers at an extrusion rate higher than 800 m/minute, formed by TFE and FMVE, having Melt Flow Index (MFI) (ASTM D 1238) from 8 g/10 min to 50 g/10 min obtained by using in the polymerization step a chain transfer agent in an amount so to obtain the above MFI, having mechanical properties unchanged after thermal aging for 7 days at 232° C., said copolymers having the following composition: FMVE in per cent by moles from 3.7% to 5.2% the percent TFE moles being the complement to 100% of the FMVE moles.
