Abstract

Una composición polimérica bimodal que comprende un homopolímero de peso molecular más bajo y un copolímero de peso molecular más alto en donde la composición polimérica bimodal tiene una densidad de alrededor de 0.930 gramos por centímetro cúbico (g/cm3) a alrededor de 0.970 g/cm3, una relación de índice de fusión de alta carga:índice de fusión de alrededor de 10 a alrededor de 150 y una resistencia al agrietamiento por estrés ambiental (ESCR) de alrededor de 25 horas a alrededor de 300 horas cuando se mide de acuerdo con ASTM D1693 o ASTM D2561. Una composición polimérica catalizada por cromo que comprende (i) un homopolímero de peso molecular más bajo y (ii) un copolímero de peso molecular más alto, en donde la composición polimérica bimodal tiene una resistencia al agrietamiento por estrés ambiental (ESCR) de alrededor de 25 horas a alrededor de 300 horas cuando se mide de acuerdo con ASTM D1693 o ASTM D2561.
