Abstract

Composición de polímero que comprende: a) un componente de polietileno de bajo peso molecular (LMW); y b) un componente de polietileno de alto peso molecular (HMW), en donde la composición tiene un pico sustancialmente único en la curva de LTD y un valor PENT mayor de alrededor de 1.000 horas a 80°C y alrededor de 2,4 MPa. Dicha composición tiene una densidad de más de 0,940 g/cm3, un peso molecular promedio de alrededor de 200.000 a 350.000 y una relación de índice de flujo a índice de fusión (I21/I5) de alrededor de 15 a 40. Procedimiento de polimerización para fabricar dicha composición que comprende: poner en contacto por lo menos una composición de catalizador con por lo menos una mezcla de alfaolefina y etileno en condiciones de polimerización en un sistema de reactor para formar una mezcla que comprende un componente de polímero de etileno/alfa-olefina de alto peso molecular y un componente de polímero de etileno/alfa-olefina de bajo peso molecular en el sistema de reactor, en donde la mezcla tiene un pico sustancialmente único en una curva de distribución de espesor laminar. Método para fabricar un cano que comprende: a) seleccionar una composición de polímero que posee un pico sustancialmente único en la curva de LTD; y b) extruir la composición de polímero para formar un cano. El cano obtenido puede emplearse para agua, gas o aceite.
