ABSTRACT:
Novel organic fluorine compounds are of formula (1): ##STR1## wherein R.sup.1 and R.sup.2 are monovalent hydrocarbon groups, Q.sup.1 is a group of formula (2) or (3): ##STR2## wherein R.sup.3 is a divalent hydrocarbon group which may have an intervening oxygen, nitrogen or silicon atom, R.sup.4 and R.sup.5 are divalent hydrocarbon groups, Rf.sup.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.
