    Abstract: The present invention relates to propylene copolymers grafted to alpha , beta -ethylenic unsaturated carboxylic acids or carboxylic acid derivatives, comprising ai) a random propylene copolymer (A1) containing from 0.1 to 15 % by weight of copolymerised C2- to C10-alk-1-enes, or a2) a propylene copolymer (A2), a random propylene copolymer (I) containing from 0.1 to 15% by weight of copolymerised C2- to C10-alk-1-enes and a random propylene copolymer (II) containing from 15 to 80% by weight of copolymerised C2- to C10-alk-1-enes, or a3) a propylene copolymer (A3) comprising a propylene homopolymer (III) and a random propylene copolymer (IV) containing from 15 to 80% by weight of copolymerised C2- to C10-alk-1-enes, obtainable by reacting the monomer to be grafted with the propylene copolymer (A1), (A2) or (A3) at pressures of from 1 to 300 bar, where, in the presence of from 0.005 to 0.5% by weight of an initiator which decomposes to give free radicals, from 0.01 to 1.0% by weight of the monomer to be grafted, where both concentrations are based on the propylene copolymer, is mixed with the molten propylene copolymer, and the grafting reaction is carried out at from 200 to 350@C.
