Abstract

La presente se relaciona con un polímero que comprende unidades derivadas de etileno, polímero que tiene: a) un índice de Fusión de 0,05 a 20 g/10 min., según determinación por la Condición E de ASTM-1238; b) por lo menos 10 por 100 átomo de C de las ramificaciones de cadena corta, que contienen cinco átomos de carbono o menos, según determinación por RMN de C13, y menos de 3,5 % en moles de unidades derivadas de un éter copolimerizable etilénicamente insaturado; c) una densidad de 0,90 a 0,94 g/cm3, preferentemente de 0,91 a 0,935 g/cm3, especialmente de 0,92 a 0,9 g/cm3, según determinación por ASTM D1505 y d) un tiempo de relajación según lo descripto en la presente de por lo menos 10 s. Dichos polímeros se obtienen por polimerización de radicales libres utilizando un agente de transferencia de cadena que se incorpora a la cadena polimérica, como por ejemplo una alfaolefina, preferentemente propileno, como agente de transferencia de cadena, preferentemente en un reactor tubular en circunstancias que favorecen la formación de RCL en una etapa posterior del reactor tubular. El polímero puede ser utilizado para película de bolsa expansible, preferentemente en forma de tubo coextruido de película soplada que comprende: a) un núcleo del mencionado polímero y b) una capa superficial, sobre cada cara del núcleo, que puede ser una composición igual o diferente y comprende por lo menos 60 % en peso de un LLDPE con una densidad de 0,91 a 0,94 g/cm3 según determinación por la condición E de ASTM-D 1238 y extraíbles en hexano, donde menos de 1,5 % en peso de dicha capa superficial contiene menos de 7500 de materiales anti-bloqueo en partículas y donde dicha película tiene una recuperación elástica después de un estiramiento del 100 % de por lo menos 40 % y otorga una fuerza de retención normalizada pro cada 100 micrones de espesor previo al estiramiento a 85 % de estiramiento después de un estiramiento inicial de 100 %, de por lo menos 20 N/50 nm. a una velocidad de deformación de menos de 10 % de la longitud de partida por segundo.
