| abstract | A CURABLE FLUOROELASTOMER COMPOSITION HAVING IMPROVED RESISTANCE TO SHRINKAGE DURING MOLDING, WHICH CURES TO A COMPOSITION HAVING OTHER DESIRABLE PROPERTIES SUCH AS GOOD TEAR STRENGTH AND ELONGATION CAN BE MADE BY MIXING THE FOLLOWING: (A) AN ELASTOMERIC COPOLYMER OF VINYLIDENE FLUORIDE AND AT LEAST ONE OTHER FLUORINATED MONOMER, (B) A POLYHDROXYLIC AROMATIC COMPOUND CROSS-LINKING AGENT FOR SAID COPOLYMER, (C) A SUITABLE VULCANIZATION ACCELERATOR, SUCH AS A QUATERNARY PHOSPHONIUM OR AMMONIUM COMPOUND, (D) A SUITABLE METAL COMPOUND SUCH AS A DIVALENT METAL OXIDE OR HYDROXIDE, AND (E) A POLYEPOXIDE HAVING A FUNCTIONALITY OF AT LEAST TWO. PARTICULARLY USEFU COMPOSITIONS OF THIS TYPE CAN BE MADE FROM COPOLYMERS OF VINYLIDENE FLUORIDE AND HEXAFLUOROPROPYLENE (POLYMERIZED IN A MOLAR RATIO OF 85:15 TO 50:50) AND, PER 100 PARTS OF COPOLYMER, 0.1-5 PARTS OF HEXAFLUOROISOPROPYLIDENE-BIS(4 - HYDROXYBENZENE), 0.1-3 PARTS OF BENZYLTRIPHENYLPHOSPHONIUM CHLORIDE, 1-20 PARTS OF MAGNESIUM OXIDE OR A MIXTURE OF MAGNESIUM AND CALCIUM OXIDES, AND 0.5-10 PARTS OF DIFUNCTIONAL EPOXY RESIN MADE FROM EPICHLOROHYDRIN AND BISPHENOL. A. CURING IS ACCOMPLISHED BY HEATING FOR 3-30 MINUTES ABOUT 149204*C. AND OPTIONALLY POSTCURING FOR 1-48 HOURS AT ABOUT 204-260*C. |
