Abstract

SE PROPORCIONA UN PROCESO MEJORADO PARA LA HIDROGENIZACION DE POLIMEROS DE DIENO CONJUGADOS QUE COMPRENDE LA POLIMERIZACION O COPOLIMERIZACION DE AL MENOS UN DIENO CONJUGADO CON UN INICIADOR DE POLIMERIZACION DE METAL ORGANO ALCALI EN UN SOLVENTE ADECUADO CREANDO A TRAVES DEL MISMO UN POLIMERO VIVO, TERMINANDO LA POLIMERIZACION MEDIANTE LA ADICION DE HIDROGENO Y EFECTUANDO LA HIDROGENIZACION SELECTIVA DE LOS ENLACES DOBLES EN LAS UNIDADES DE DIENO CONJUGADAS DEL POLIMERO TERMINADO MEDIANTE EL CONTACTO DEL POLIMERO, EN LA AUSENCIA DE COMPUESTOS DE LITIO DE HIDROCARBONO Y LITIO DE ALCOXI, CON HIDROGENO EN LA PRESENCIA DE AL MENOS UN COMPUESTO DE BIS-(CICLOPENTADIENIL)TITANIO. LA MEJORA ES EL USO DE BENZOATO DE ALQUILO COMO UN PROMOTOR EN LA FASE DE HIDROGENIZACION. EL BENZOATO DE METILO ES EL PROMOTOR MAS PREFERIDO.
