摘要
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)perfluoroalkane a with sodium azide gave the corresponding alpha,omega-bis(azidoethyl)perfluoroalkanes. Hydrogenation of the alpha,omega-bis(azidoethyl)perfluoroalkanes gave diamines. Phosgenation of the amino groups gave diisocyanates.
