CATALYSTS CONTAINING METALOCENES WITH ARILSUBSTITUID INDENILE DERIVATIVES AS LEGENDS, PROCEDURES AND INTERMEDIATE PRODUCTS FOR THE OBTAINING OF THESE METALOCENES, AND THEIR EMPLOYMENT.
A VERY ACTIVE CATALYZER SYSTEM FOR POLYMERIZATION OR COPOLYMERIZATION OF OLEFINS IS COMPOSED OF A COCATALIZER, PREFERRED TO A SUPPORTED ALUMINOXANE, AND A METALLOCENE OF FORMULA I WHERE PREFERREDLY M {SUP, 1} MEANS ZR OR SUPPLIES 1} YR {SUP, 2} MEAN HALOGEN OR RENT, R {SUP, 3} IT'S RENT, R {SUP, 4} UNTIL R {SUP, 12} IT'S RENT OR HYDROGEN YR {SUP, 13} IT'S AN ALKYLENE BRIDGE ( REPLACED) OR A HETEROATOMO BRIDGE. THE METALOCENOS, IN PARTICULAR THE ZIRCOCENES, GENERATE IN THE AREA OF SPECIALLY INTERESTING TEMPERATURE OF TECHNICAL FORM BETWEEN 50 AND 80 DAYS OF CATALYST WITH VERY HIGH MOLAR MASS, IN CASE OF PROQUIRAL MONOMERY POLYMERS, WITH VERY HIGH MOLAR MASS, AND HIGH FUSION POINT. FOR THIS, REACTOR APPLICATION WITH SUPPORTED CATALYST SYSTEMS IS AVOIDED.
