Difunctional Monomers Based on Perfluoropropylene Telomers

reportActive / Technical Report | Accession Number: ADA283677 | Open PDF

Abstract:

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-bisiodoethylperfluoroalkanes, which were converted to the corresponding diols by reaction with fuming sulfuric acid. The reaction of the branched-chain alpha,omega-bisiodoethyl-perfluoroal with sodium azide gave the corresponding alpha,omega-bis-azidoethyl-perfluoroaHydrogenation of the alpha,omega- bisazidoethyl-perfluoroalkanes gave diamines. Phosgenation of the amino groups gave diisocyanates. Synthesis, Monomers, Fluorine
