Beschreibung
Zusammenfassung:	The invention relates to a polypropylene based nucleating agent masterbatch and a preparation method thereof. The masterbatch is composed of, by weight, 2 to 60 wt. % of diurea based nucleating agent, 40 to 98 wt. % parts of polypropylene resin. The present invention discloses a process for preparation of a polypropylene masterbatch by mixing polypropylene with a nucleating agent as represented in FIG. 2. According to the invention, the prepared polypropylene masterbatch has the advantages of being a masterbatch which can be added in any grade of polypropylene, does not cause inhalation hazards while handling, is easy to handle and has improved dispersion in the base polypropylene.
