Copolymers of cyclopentadiene

Claim 1

THE METHOD OF PREPARING A HOMOGENEOUS COPOLYMER OF A CYCLOPENTADIENE AND A MONO-OLEFIN COMPRISING THE STEPS IN COMBINATION OF PREPARING A MIXTURE CONTAINING A SUBSTANTIAL EXCESS OF THE MONO-OLEFIN, SUFFLICIENT TO PRODUCE A COPOLYMER CONTAINING THE DESIRED MAJOR AMOUNT OF THE CYCLOPENTADIENE, COOLING THE MIXTURE TO A TEMPERATURE WITHIN THE RANGE BETWEEN -10*C. AND -164*C. IN THE PRESENCE OF A DILUENT-SOLVENT FOR THE MONO-OLEFIN AND CYCLOPENTADIENE COMPOUND, STARTING THE FLOW INTO THE COLD MIXTURE OF A SMALL STREAM OF FLUID FRIEDEL-CRAFTS ACTIVE METAL HALIDE CATALYST, AND SIMULTANEOUSLY STARTING THE FLOW INTO THE MIXTURE OF A SMALL STREAM OF MIXED CYCLOPENTADIENE COMPOUND AND MONO-OLEFIN, MIXED IN THE PROPORTION DESIRED IN THE FINISHED POLYMER, THE STREAM OF MIXED OLEFINS BEING DELIVERED AT APPROXIMATELY THE RATE AT WHICH POLYMERIZATION IS TAKING PLACE, WHEREBY A SUFFICIENT EXCESS OF MONO-OLEFIN IN MAINTAINED IN THE MIXTURE TO FORCE INTO THE COPOLYMER THE DESIRED AMOUNT OF MONO-OLEFIN TO PRODUCE A COPOLYMER CONTAINING IN THE POLYMER MOLECULE A MAJOR PROPORTION OF THE CYCLENTADIENE, THE COPOLYMER BEING CHARACTERIZED BY A STAUDINGER MOLECULAR WEIGHT NUMBER WITHIN THE RANGE BETWEEN 3,000 AND 100,000; AN IODINE NUMBER WITHIN THE RANGE BETWEEN 50 AND 300; REACTIVITY WIDTH SULFUR IN A CURING REACTION TO REDUCE THE HYDROCARBON SOLUBILITY AND REACTIVITY WITH ATMOSPHERIC OXYGEN IN A DRYING REACTION.
