摘要：The present invention concerns a method for grafting a copolymer onto apolyolefin substrate. The method comprises the following steps: (a) irradiating the saidsubstrate with ionizing radiation to obtain an activated polyolefin substrate, (b) bringinginto contact the activated polyolefin substrate with a mixture of at least two compoundsin distilled water comprising: (i) from 10 to 40% by volume, related to the total volume ofthe reaction medium, of a h drophilic unsaturated monomer selected from monomershavin the formula (I) wherein R1 is H or methyl, R2 is -COOH, -NH2, -CON(R3)2, and R3 is Hor methyl, (ii) from 20 to 50% by volume, related to the total volume of the reactionmedium, of an antimicrobial agent having an average molecular weight of at least 200g.mol-1, to thereby form a copolymer-grafted polyolefin substrate. The invention alsorelates to copolymer-grafted polyolefin substrates obtained by this method and to apackaging material comprising copolymer-grafted polyolefin substrate according to theinvention.
