Abstract: The invention relates to a process for the preparation of a crosslinkable propylene polymer composition comprising melt mixing and reacting, preferably in an extruder, a heterophasic propylene copolymer composition A, at least one crosslinkable grafting component B represented by the formula R1SiR2qY3-q and a radical initiator C. The invention also relates to the moisture cross-linkable polypropylene polymer composition obtainable by the process, to a cross-linked polypropylene polymer composition, to the use of the cross-linkable composition for the manufacture of adhesives, sealants, films, foams, coatings or shaped articles and the use of the crosslinked propylene polymer composition in food packaging, medical devices, textile packaging, technical films and protection films.
