Abstract

POR POLIMERIZACION O COPOLIMERIZACION DE UNA OLEFINA, DE FORMULA RA-CH=CH-RB EN PRESENCIA DE UN CATALIZADOR CONSTITUIDO POR UN METALOCENO, DE FORMULA I (FORMULA) EN DONDE M1 ES TITANIO, CIRCONIO, VANADIO, NIOBIO O TANTALO, CON UN ALUMINOXANO, SE OBTIENE, CON ELEVADO RENDIMIENTO, UNA POLIOLEFINA SINDIOTACTICA. ESTA POLIOLEFINA TIENE UNA MASA MOLAR MUY ELEVADA, UN REPARTO MOLAR MUY ESTRECHO Y UNA SINDIOTAXIA MUY ALTA. LOS CUERPOS MOLDEADOS PRODUCIDOS CON ESTOS POLIMEROS SE CARACTERIZAN POR UNA ELEVADA TRANSPARENCIA, FLEXIBILIDAD, RESISTENCIA AL DESGARRE Y UN EXCELENTE BRILLO SUPERFICIAL.
