    Abstract: Propylene copolymers which comprise a randomly distributed propylene copolymer (I) containing from 0.1 to 15 % by weight of copolymerised C2- to C10-alk-1-enes and a randomly distributed propylene copolymer (II) containing from 15 to 80 % by weight of copolymerised C2- to C10-alk-1-enes, and have been grafted by means of alpha , beta -ethylenically unsaturated carboxylic acids or carboxylic acid derivatives, and are obtainable by reacting the graft monomer with the propylene copolymer 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 form free radicals, from 0.01 to 1.0 % by weight of the monomer to be grafted on, where both concentrations are based on propylene copolymer, is mixed with the molten propylene copolymer, and the grafting reaction is carried out at from 200 to 350 DEG C.
