    摘要: The instant invention is a polypropylene composition, a method of producing the same, and articles made therefrom. The polypropylene composition according to instant invention includes the reactive melt blending product of a high crystalline polypropylene having a crystallinity of at least 64 percent, an elastomer, a coupling agent, and optionally a filler. The polypropylene composition according to instant invention has a melt flow rate in the range of less than 1 g/10 minutes measured at 230° C. under a load of 2.16 kg in accordance with ASTM-D 1238. The method of producing a polypropylene composition according to instant invention includes the following steps: (1) reactive melt blending a high crystalline polypropylene having a crystallinity of at least 64 percent, an elastomer, and optionally a filler in the presence of a coupling agent; and (2) thereby producing the polypropylene composition having a melt flow rate in the range of less than 1 g/10 minutes measured at 230° C. under a load of 2.16 kg in accordance with ASTM-D 1238. The articles according to instant invention include the inventive polypropylene composition including the reactive melt blending product of a high crystalline polypropylene having a crystallinity of at least 64 percent, an elastomer, a coupling agent, and optionally a filler.
