Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
54 words
A VULCANIZABLE COMPOSITION COMPRISING A MAJOR PROPORTION OF A RUBBERY HALOGENATED COPOLYMER OF ABOUT 85 TO 99.5 WEIGHT PERCENT OF A C4 TO C7 ISSOLEFIN AND ABOUT 15 TO 0.5 WEIGHT PERCENT OF A C4 TO C14 MULTIOLEFIN AND A VULCANIZING AMOUNT OF A HEXAHYDRODIAZINE, SAID COPOLYMER CONTAINING AT LEAST 0.5 WEIGHT PERCENT HALOGEN.
Claim 2
Dependent Claim
54 words
A VULCANIZABLE COMPOSITION COMPRISING A MAJOR PROPORTION OF A RUBBERY HALOGENATED COPOLYMER OF ABOUT 85 TO 99.5 WEIGHT PERCENT OF A C4 TO C7 ISSOLEFIN AND ABOUT 15 TO 0.5 WEIGHT PERCENT OF A C4 TO C14 MULTIOLEFIN AND A VULCANIZING AMOUNT OF A HEXAHYDRODIAZINE, SAID COPOLYMER CONTAINING AT LEAST 0.5 WEIGHT PERCENT HALOGEN.
Claim 3
Dependent Claim
140 words
A COMPOSITION COMPRISING A RUBBERY POLYMER HAVING A VISCOSITY AVERAGE MOLECULAR WEIGHT OF A LEAST ABOUT 100,000 COMPRISING ATOMS OF HYDROGEN, CARBON AND A HALOGEN SELECTED FROM THE GROUP CONSISTING OF FLUORINE, CHLORINE, BROMINE, IODINE AND MIXTURES THEREOF, CONTAINING IN ITS STRUCTURE A MAJOR PROPORTION OF HYDROCARBON UNITS DERIVED BY THE POLYMERIZATION OF ISOOLEFINS CONTAINING ABOUT 4 TO 7 CARBON ATOMS AND ALSO CONTAINING SUFFICIENT UNITS IN WHICH A PAIR OF CARBON ATOMS IS LINKED BY AN OLEFINIC DOUBLE BOND THAT THE MOLE PERCENT UNSATURATION IS BETWEEN ABOUT 0.5 AND 15, SAID POLYMER CONTAINING AT LEAST ABOUT 0.5 WEIGHT PERCENT HALOGEN BUT NOT MORE THAN ABOUT ONE COMBINED ATOM OF HALOGEN PER DOUBLE BOND IN THE POLYMER, SAID POLYMER BEING IN COMPOSITION WITH A VULCANIZING AMOUNT OF A HEXAHYDRODIAZINE, SAID COMPOSITION BEING FREE OF SULFUR, ZINC OXIDE AND ALICYCLIC AMINES.
Claim 4
Dependent Claim
140 words
A COMPOSITION COMPRISING A RUBBERY POLYMER HAVING A VISCOSITY AVERAGE MOLECULAR WEIGHT OF A LEAST ABOUT 100,000 COMPRISING ATOMS OF HYDROGEN, CARBON AND A HALOGEN SELECTED FROM THE GROUP CONSISTING OF FLUORINE, CHLORINE, BROMINE, IODINE AND MIXTURES THEREOF, CONTAINING IN ITS STRUCTURE A MAJOR PROPORTION OF HYDROCARBON UNITS DERIVED BY THE POLYMERIZATION OF ISOOLEFINS CONTAINING ABOUT 4 TO 7 CARBON ATOMS AND ALSO CONTAINING SUFFICIENT UNITS IN WHICH A PAIR OF CARBON ATOMS IS LINKED BY AN OLEFINIC DOUBLE BOND THAT THE MOLE PERCENT UNSATURATION IS BETWEEN ABOUT 0.5 AND 15, SAID POLYMER CONTAINING AT LEAST ABOUT 0.5 WEIGHT PERCENT HALOGEN BUT NOT MORE THAN ABOUT ONE COMBINED ATOM OF HALOGEN PER DOUBLE BOND IN THE POLYMER, SAID POLYMER BEING IN COMPOSITION WITH A VULCANIZING AMOUNT OF A HEXAHYDRODIAZINE, SAID COMPOSITION BEING FREE OF SULFUR, ZINC OXIDE AND ALICYCLIC AMINES.
Claim 5
Dependent Claim
32 words
A COMPOSITION ACCORDING TO CLAIM 8 IN WHICH THE POLYMER IS ALSO IN COMPOSITION WITH ABOUT 5.0 TO 150 PARTS BY WEIGHT OF A FILLER PER 100 PARTS BY WEIGHT OF POLYMER.
