POLYMERIZATION PROCESS TO PRODUCE A POLYOLEFINE ELASTOMERO, CATION GENERATOR COCATALIZER TO ACTIVATE A METALOCENE PROCESSOR, POLYOLEFINE ELASTOMERO THAT HAS A UNIQUE COMBINATION OF PROPERTIES AND PRODUCTS MANUFACTURED.

摘要

THE INVENTION REFERS TO A POLYOLEFINE ELASTOMERO THAT HAS A UNIQUE COMBINATION OF PROPERTIES, THAT IS, ELEVATED MOLECULAR WEIGHT (MW), MOONEY VISCOSITY (ML 1 + 4, at 125 ° C), LOW POLIDISPERSITY INDEX (MW / MN), LOW VITREA TRANSITION TEMPERATURE (TG) AND LOW HYSTERESIS (TAN DE). SUCH ELASTOMERO IS OBTAINED BY A POLYMERIZATION PROCEDURE THAT USES A PARTICULAR TYPE OF METALOCENE CATALYST. THE APPOINTMENT ELASTOMERO IS USEFUL FOR THE MANUFACTURE OF DIFFERENT PRODUCTS, INCLUDING RUBBER ITEMS, LIKE FLEXIBLE PIPES, BANDS AND MOLDED PARTS, POLYMER MIXTURES CONTAINING ONE OR MORE DIFFERENT HYDROCARBON POLYMERS AND THE OIL THAT FUNCTIONS THE LUBRICATION OF THE MODE FOR THE LUBRICATION OF THE MODE. . Also, an ION GENERATOR COCATALIZER FOR THE ACTIVATION OF A METALOCENE CATALYST IS DESCRIBED, PREFERIBLY IN THE PRESENCE OF AN OLEFINICAL MONOMERO.
