Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 191 words
An adhesive composition for fluorinated rubbers which comprises; a fluorine-containing epoxy compound of the formula: ##STR5## wherein Rf is a fluoroalkylene group having 1 to 18 carbon atoms or a fluorophenylene group, R is a single bond, an alkylene group having 1 or 2 carbon atoms and optionally bearing at least one fluorine atom, an oxyalkylene group having 1 or 2 carbon atoms and optionally bearing at least one fluorine atom or an oxyphenylene group optionally bearing at least one fluorine atom or at least one trifluoromethyl group on the benzene ring; and a silane compound of the formula: R.sup.1 SiR.sub.3-y.sup.2 R.sub.y.sup.3 wherein R 1 is an alkyl or alkenyl group having 1 to 10 carbon atoms, which is optionally substituted with at least one member of the group consisting of chlorine, amino, aminoalkyl, ureido, epoxyoxy, glycidoxy, epoxycyclohexyl, acryloyloxy, methacryloyloxy, mercapto and vinyl, R 2 and R 3 are each chlorine, hydroxyl, C 1 -C 10 alkoxy, C 1 -C 5 alkoxy (C 1 -C 5 ) alkoxy, hydroxy (C 2 -C 4 ) alkoxy or C 1 -C 5 acyloxy and y is an integer of 0, 1 or 2.
Claim 2
Dependent Claim 191 words
An adhesive composition for fluorinated rubbers which comprises; a fluorine-containing epoxy compound of the formula: ##STR5## wherein Rf is a fluoroalkylene group having 1 to 18 carbon atoms or a fluorophenylene group, R is a single bond, an alkylene group having 1 or 2 carbon atoms and optionally bearing at least one fluorine atom, an oxyalkylene group having 1 or 2 carbon atoms and optionally bearing at least one fluorine atom or an oxyphenylene group optionally bearing at least one fluorine atom or at least one trifluoromethyl group on the benzene ring; and a silane compound of the formula: R.sup.1 SiR.sub.3-y.sup.2 R.sub.y.sup.3 wherein R 1 is an alkyl or alkenyl group having 1 to 10 carbon atoms, which is optionally substituted with at least one member of the group consisting of chlorine, amino, aminoalkyl, ureido, epoxyoxy, glycidoxy, epoxycyclohexyl, acryloyloxy, methacryloyloxy, mercapto and vinyl, R 2 and R 3 are each chlorine, hydroxyl, C 1 -C 10 alkoxy, C 1 -C 5 alkoxy (C 1 -C 5 ) alkoxy, hydroxy (C 2 -C 4 ) alkoxy or C 1 -C 5 acyloxy and y is an integer of 0, 1 or 2.
Claim 3
Dependent Claim 14 words
The adhesive composition according to claim 1, wherein R 1 is an aminoalkyl group.
Claim 4
Dependent Claim 27 words
The adhesive composition according to claim 1, wherein the weight proportion of the fluorine-containing epoxy compound and the silane compound is from about 95:5 to about 30:70.
