Abstract

Un procedimiento para preparar copolímeros de etileno que tienen una amplia distribución del peso molecular, caracterizado porque se lleva a cabo en presencia de mezclas estereoisoméricas meso- y rac- de compuestos de metaloceno que tienen la fórmula general (1), en la cual A' y A'', iguales o diferentes, son un radical de tipo h5-tetrahidroindenilo de fórmula (2). Reivindicación 1: Mezclas estereoisoméricas meso- y rac- de compuestos de metaloceno que tienen la fórmula general (1), caracterizadas porque: M se selecciona entre titanio, zirconio, hafnio; X1 y X2, iguales o diferentes, se seleccionan entre halógeno, amida, carboxi, alcoxi, carbamato, alquilo, arilo, hidrógeno; A' y A'' iguales o diferentes, son un radical de tipo h5-tetrahidroindenilo de fórmula (2) en la cual los grupos R5, R6, R7, R8, R9, R10, iguales o diferentes, se seleccionan entre hidrógeno, un radical alifático C1-8, un radical cicloalifático C5-12, un radical arilo C6-14; los grupos R1, R2, R3 y R4, iguales o diferentes, se seleccionan entre hidrógeno, un radical alifático C1-8, un radical cicloalifático C5-12, un radical arilo C6-14, halógeno.
