摘要： A 5-(1''-ALKENYL)-2-NORBORNENE, SUITABLE AS ONE OF THE COMPONENTS OF AN ETHYLENE-PROPYLENE-DIENE TERPOLYMER, HAVING THE FORMULA,

5-(R2-CH2-C(-CH3)=C(-R1)-)-2-NORBORNENE

WHEREIN R1 AND R2 EACH ARE HYDROGEN ATOMS OR LINEAR ALKYL GROUPS, IS ADVANTAGEOUSLY PREPARED BY ISOMERIZING IN THE PRESENCE OF A CATALYST A 5-(2''-ALKENYL)-2-NORBORNENE HAVING THE FORMULA,

5-(R2-CH=C(-CH3)-CH(-R1)-)-2-NORBORNENE

WHEREIN R1 AND R2 ARE SAME AS ABOVE.

摘要： A linear copolymer having a high sulfur curing rates is prepared by contacting substantially exo-type 5-alkenyl-2-norbornene compound and ethylene and/or Alpha -olefin having three to 20 carbon atoms with a catalyst consisting essentially of an organoaluminum compound and vanadium compound and/or titanium compound, both said vanadium compound and titanium compound having at least trivalencies, in the presence or absence of an inactive reaction medium. Particularly, terpolymers comprising ethylene, propylene and substantially exo-type 5-alkenyl-2norbornene have excellent characteristics as elastomers.

摘要： 5-ISOPROPYLIDENE-2-NORBORNENE IS PRODUCED BY SUBJECTING CYCLOPENTADIENE AND 2-METHYL-3-BUTENE-2-OL TO DIELSALDER REACTION TO OBTAIN A,A-DIMETHYL-5-NORBORNENE-2METHANOL (A MIXTURE OF ENDO-FORM AND EXO-FORM), DEHYDRATING THE A,A-DIMETHYL-5-NORBORNENE-2-METHANOL TO FORM A MIXTURE OF ENDO- AND EXO-5-ISOPROPENYL-2-NORBORNENE MIXTURE CONTAINING, IN PART, 5-ISOPROPYLIDENE-2-NORBORNENE, AND CONTACTING THE MIXTURE WITH AN ALKALINE CATALYST. THE 5-ISOPROPYLIDENE-2-NORBORNEN IS USEFUL AS A TERMONOMER OF A SO-CALLED ETHYLENE-PROPYLENE TERPOLYMER RUBBER, AND THE INCORPORATION THEREOF RESULTS IN A TERPOLYMER HAVING EXCELLENT CURING CHARACTERISTICS.
