Abstract

LA INVENCION PRESENTA UN CATALIZADOR Y UN PROCESO PARA LA HIDROGENACION DE POLIMEROS DE DIOLEFINA CONJUGADA QUE CONSISTE PRIMERO EN LA POLIMERIZACION O COPOLIMERIZACION DE DICHOS MONOMEROS CON UN INICIADOR DE POLIMERIZACION DE UN ORGANOMETAL ALCALINO EN UN SOLVENTE ADECUADO CREANDO ASI UN POLIMERO VIVO. EL POLIMERO VIVO SE TERMINA PREFERENTEMENTE CON LA ADICION DE HIDROGENO. FINALMENTE, LA HIDROGENACION SELECTIVA DE LOS ENLACES DOBLES NO SATURADOS EN LAS UNIDADES DE DIOLEFINA CONJUGADA DEL POLIMERO TERMINADO SE LLEVA A CABO ANTE LA PRESENCIA DE UN COMPUESTO DE BIS (CICLOPENTADIENIL)-TITANIO (+3) QUE TIENE LA FORMULA: (C SUB 5 R" SUB 5) SUB 2 DEL GRUPO QUE CONSISTE EN ALQUILO, ARALQUILO, ALILO, ARILO, ALCOXI, ALOGENO, SILILO O AMINA Y R", QUE PUEDE SER IGUAL O DIFERENTE, SE SELECCIONA DEL GRUPO QUE CONSISTE EN HIDROGENO, ALQUILO, ARALQUILO O ARILO.
