COPOLYCONDENSATION POLYMERIZATION OF FLUOROPOLYMERS

Résumé

This invention relates to a copolycondensation polymerization process for the manufacture of fluorinated copolymers wherein A) a telechelic fluoroazido compound of formula N3(Y)p-(CH2)n-R-(CH2)m-(Y)pN3, wherein Y is SO, SO2, C6H4, or CO, p = 0 or 1, n and m are independently 1 to 4, and R is selected from the group consisting of i) a C3 - C10 fluoroalkylene group, ii) a C3 - C10 fluoroalkoxylene group, iii) a substituted aryl group, iv) an oligomer of poly(vinylidene fluoride-co-perfluoro(methyl vinyl ether)), v) an oligomer of poly(vinylidene fluoride-co-hexafluoropropylene) and vi) an oligomer of poly(tetrafluoroethylene-co-perfluoro(methyl vinyl ether)) is reacted with B) a telechelic diyne or dinitrile compound in the presence of copper halide catalyst.
