Organic fluorine compounds and curable compositions containing them

摘要

Novel organic fluorine compounds are of formula (1): <CHEM> wherein R<1> and R<2> are monovalent hydrocarbon groups, Q<1> is a group of formula (2) or (3): <CHEM> <CHEM> wherein R<3> is a divalent hydrocarbon group which may have an intervening oxygen, nitrogen or silicon atom, R<4> and R<5> are divalent hydrocarbon groups, Rf<1> is a divalent perfluoroalkylene or perfluoropolyether group, and letter a is an integer of 0-10. A curable composition comprising (A) a fluorinated amide compound having at least two aliphatic unsaturated groups of formula (1), (B) a fluorinated organohydrogensiloxane containing at least one monovalent perfluoroalkyl ether or perfluoroalkyl group and at least two hydrosilyl groups, and (C) a platinum group compound cures into elastomers solvent and chemical resistance.
