ABSTRACT:
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).
