摘要： A method for producing a fluorinated polymer containing fluoroolefin units as the main constituting units, wherein CF.sub.3 (CF.sub.2).sub.n CH.sub.2 CH.sub.3 or CF.sub.3 (CF.sub.2).sub.n H, wherein n is an integer of from 1 to 8), the is used as the polymerization medium, and CF.sub.2 ClCF.sub.2 CHClF and/or CF.sub.3 CF.sub.2 CHCl.sub.2 as a chain transfer agent.Using the polymerization medium which is less likely to bring about an environmental destruction, it is possible to obtain a fluorinated polymer excellent in the heat resistance, solvent resistance, chemical resistance, etc. Further, the above chain transfer agent has good compatibility with the polymerization medium which scarcely brings about the environmental destruction, whereby it is possible to efficiently produce a fluorinated polymer excellent in the heat resistance and solvent resistance. This chain transfer agent has affinity to the resulting polymer and to the polymerization medium and has excellent handling efficiency for post treatment such as granulation or drying.
