Abstract
Cyclopentanes alkyl-substituted with one or more C.sub.1 -C.sub.6 alkyls are used as chain transfer agents in (co)polymerization reactions carried out, either in suspension or in aqueous emulsion, at low temperatures, comprised between -30.degree. and +30.degree. C., for preparing thermoplastic hydrogen-containing fluoropolymers , such as for instance ethylene/chlorotrifluoroethylene and ethylene/tetrafluoroethylene copolymers, or homopolymers and copolymers of vinylidenefluoride. They are transfer agents having high efficiency, which are liquid and thus can be easily handled and dosed, non-toxic, yielding alkyl end groups of high thermal stability.
