Interpolymerization of a mixture of monoolefins and a polyene in the presence of certain bases
Abstract
Abstract SULFUR VULCANIZABLE ELASTOMES HAVING IMPROVED CHARACTERISTICS ARE PREPARED BY INTERPOLYMERIZING A MONOMERIC MIXTURE CONTAINING ETHYLENE, AT LEAST ONE ALPHAMONOOLEFIN CONTAINING 3-16 CARBON ATOMS, AND AT LEAST ONE POLYENE IN A HYDROCARBON POLYMERIZATION SOLVENT, AND IN THE PRESENCE OF A ZIEGLER CATALYST AND CERTAIN BASES SUCH AS AMMONIA, ANILINE AND PYRIDINE. THE ELASTOMERS ARE SOLUBLE IN THE HYDROCARBON SOLVENT, AND ARE FREE OF DELETERIOUS GEL OR CROSSLINKING AND OTHER UNERSIABLE FORMS OF POLYMERIZATION. THE PROPERTIES OF THE ELASTOMER ARE REPRODUCIBLE AND A UNIFORM PRODUCT MAY BE PRODUCED ON A CONTINUOUS BASIS. THE CATALYST MILEAGE IS ALSO INCREASED MARKEDLY WHEN USING CERTAIN PREFERRED BASES.
