| 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 R 1 SiR 2 q Y 3-q and a radical initiator C. The invention also relates to the moisture cross-linkable polypropylene polymer composition obtainable by the process, to cross-linked polypropylene polymer product having high flexibility and strength, to the use of the cross-linkable composition for the manufacture of adhesives, films, foams, coatings or shaped articles and the use thereof in food packaging, medical devices etc. |
