Popis:	Telomers of perfluoropropylene with alpha,omega- diiodoperfluoroalkanes were converted to branched-chain difunctional condensation monomers. The reaction of ethylene with the telomers gave alpha, omega-bis(iodoethyl)perfluoroalkanes, which were converted to the corresponding diols by reaction with fuming sulfuric acid. The reaction of the branched-chain alpha,omega-bis(iodoethyl)-perfluoroal with sodium azide gave the corresponding alpha,omega-bis-(azidoethyl)-perfluoroaHydrogenation of the alpha,omega- bis(azidoethyl)-perfluoroalkanes gave diamines. Phosgenation of the amino groups gave diisocyanates. Synthesis, Monomers, Fluorine
