Crosslinking of Perfluorocarbon Polymers

Abstract

Crosslinking investigations of perfluorinated systems employing metalloid compound initiated thermal cure and a functional epoxide approach are reported. Using triphenylphosphine and tetraphenyldiphosphine at temperatures up to 300 C, no reaction was observed with perfluoroalkylethers; with perfluoro(methylcyclohexane) some fluorine abstraction took place but no coupling products could be identified. The presence of aromatic substituents resulted in perfluoroalkylether chain activation. A functional epoxide precursor, 4-bromoheptafluorobutene-1 was prepared and the Procedure for its oxidation to the epoxide was optimized.
