Additives for hydrogenated resins obtainable by using the following components: a) bifunctional perfluoropolyethers having a -COOR end group, optionally in admixture with monofunctional perfluoropolyethers having a -COOR end group, b) mono, bi or polyfunctional hydrogenated monomers having functional groups able to react with the -COOR end groups of compound a); c) polyolefins having functional groups able to react with the block oligomer/polymer obtained by reaction of a) with b), preferably said functional groups being obtained by grafting with maleic anhydride; reacting in a first step a) with b), until disappearance of the -COOR group of component a), and in a second step the product obtained from the reaction of a) with b) with the functionalized polyolefins c).
