Abstract

Esta invencion está relacionada a catalizadores novedosos la estructura y actividad de los cuales, puede ser controlada para producir un rango amplio de polímeros de alfaolefina y copolímeros y de preferencia para la produccion de poliolefinas de estereobloque, que comprende un rango amplio de segmentos amorfo y cristalino preseleccionados para el control preciso de sus propiedades físicas, principalmente propiedades termoplásticas, elastoméricas. Más específicamente, esta invencion está relacionada a catalizadores y sistemas catalizadores nuevos para la produccion de polipropileno de estereobloque que comprende diasterosecuencias isotácticas y atáctica alternantes, lo cual resulta en un rango amplio de propiedades elastoméricas. La cantidad y numeros de secciones cristalinas, el contenido de péntada isotática, el numero y longitud de cadenas atácticas intermedias y el peso molecular total todos son controlables por la estructura estérica de los catalizadores y las condiciones del proceso. Los catalizadores nuevos proporcionados por la presente invencion, son metalocenos no rígidos que portan el ligando, la geometría del cual puede ser controlada en una escala de tiempo que es más lenta que la velocidad de insercion de la olefina, pero más rápida que el tiempo promedio para construir (polimerizar) una cadena de polímero individual, para obtener una estructura de estereobloque en las poliolefinas producidas. La simetría de la estructura del catalizador es tal que por la isomerizacion, la simetría del catalizador se alterna entre una geometría aquiral. Esta alteracion de la geometría puede ser controlada seleccionando el tipo y estructura del ligando y por medio del control de las condiciones de polimerizacion para controlar precisamente las propiedades físicas de los polímeros resultantes.
