Abstract

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.
