Abstract
Se proporcionan copolímeros, y procesos para hacerlos, los cuales son derivados de monomeros, comprendiendo: A) una mono-olefina que tiene un solo enlace ziegler-natta polimerizable; B) un segundo monomero que tiene al menos un enlace ziegler-natta polimerizable; C) un tercer monomero que tiene al menos dos enlaces ziegler-natta polimerizables, tal monomero siendo: I) de cadena recta y de menos de seis o al menos siete átomos de carbono; II) distinto de cadena recta; o III) sus combinaciones; tal copolímero teniendo: C) al menos alrededor de un enlace carbono-carbono insaturado por molécula promedio numérico; D) energía viscosa de activacion (EA) de al menos 1 kcal/mol mayor que un copolímero que tiene una columna vertebral lineal derivado de los mismos monomeros, pero excluyendo especies que tienen al menos dos enlaces ziegler-natta polimerizables; E) un nivel de cristalinidad de alrededor de 10 a alrededor de 50%; y F) mz/mw de al menos alrededor de 1.7. Tales copolímeros muestran una mejorada capacidad de procesamiento en estado fundido y otros atributos durante la fabricacion de productos finales.
