Abstract: An adhesive polymer composition comprising a non-elastomeric copolymer of ethylene and one or more comonomers having 3 to 10 carbon atoms, and an elastomer is disclosed herein. The non-elastomeric copolymer is present in an amount of 60 to 95% by weight, based on the adhesive polymer composition, has a weight average molecular weight Mw of from 50 000 to 80 000 g/mol, molecular weight distribution Mw/Mn of 2.0 to 5.5, density of from 0.925 to 0.945 g/cm3, and at most 0.1 vinyl groups/1000 carbon atoms. The non-elastomeric copolymer or the non-elastomeric copolymer and the elastomer have been grafted with an acid grafting agent.

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.
