Abstract
A fluorine-containing elastomer composition comprising a fluorine-containing elastomer, at least one of oxides and hydroxides of divalent metal, a polyhydroxyaromatic compound, and a quaternary ammonium salt compound represented by the general formula: ##STR1## and, if desired, further containing at least one of 1,8-diazabicyclo(5,4,0)-undec-7-en, 1,5-diazabicyclo(4,3,0)-non-5-en and 4-dialkylaminopyridine has good storage stability and vulcanization characteristics as green elastomer composition and gives distinguished physical properties to the vulcanized products.
Claims17
A fluorine-containing elastomer composition which comprises:
- (a) 100 parts by weight of a fluorine-containing elastomer,
- (b) 1 to 40 parts by weight of at least one of oxides and hydroxide of divalent metal, (c) 0.5 to 10 parts by weight of a polyhydroxyaromatic compound, and (d) 0.1 to 10 parts by weight of a quaternary ammonium salt compound represented by the following general formula (I):
- ##STR4## wherein R is an aralkyl group having 7 to 20 carbon atoms, R' is an alkyl group having 1 to 24 carbon atoms, an aryl group having 6 to 24 carbon atoms or an aralkyl group having 7 to 20 carbon atoms, X.sup.- is an anion, and n is an integer of 1 to 5.
A fluorine-containing elastomer composition, which comprises (a) 100 parts by weight of a fluorine-containing elastomer, (b) 1 to 40 parts by weight of at least one of oxides and hydroxides of divalent metal, (c) 0.5 to 10 parts by weight of a polyhydroxyaromatic compound, (d) 0.1 to 10 parts by weight of a quaternary ammonium salt compound represented by the general formula (I):
- ##STR5## and (e) at least one of such an amount of 1,8-diazabicyclo (5,4,0)-undec-7-en, 1,5-diazabicyclo(4,3,0)-non-5-en and 4-dialkylaminopyridine whose alkyl group has 1 to 4 carbon atoms as to substantially fail to vulcanize the fluorine-containing elastomer.
