Beschreibung
Zusammenfassung:	The present application refers to a process for the modification of polypropylene, wherein amount, size and configuration of the branches are controlled, the process comprising the steps of (A) preparing a bis(sulphonazide) (BSA) masterbatch by dispersing BSA in polyolefin; (B) adding (i) at least one fatty acid salt with metal cation having valence of 1+ to 3+; and (ii) the BSA masterbatch prepared in step (A) to the polypropylene to be modified. Said modified polypropylene of the present invention possesses properties suitable for use in foaming, blowing, thermoforming, recoating, film extrusion, BOPP, spinning processes and other processes and applications, and it is also suitable to be in contact with food products.
