Polypropylene polymer compositions are disclosed that can be used to produce different types of molded articles, such as extruded piping structures. The polypropylene polymer composition contains a polypropylene random copolymer in combination with a property enhancing agent. The property enhancing agent is incorporated into the polymer composition so that the composition has relatively high impact resistance properties in combination with a relatively high flexural modulus. 本发明公开了聚丙烯聚合物组合物，该聚丙烯聚合物组合物可用于生产不同类型的模塑制品，诸如挤出管道结构。该聚丙烯聚合物组合物含有聚丙烯无规共聚物与特性增强剂的组合。将特性增强剂掺入该聚合物组合物中，使得该组合物具有相对高的抗冲击特性和相对高的挠曲模量。
