Abstract:
Additives for hydrogenated resins, formed by functionalized perfluoropolyethers and functionalized polyolefins, said additives being obtained by reacting the following components:a) bifunctional perfluoropolyethers having a â€”COOR end group optionally in admixture with monofunctional perfluoropolyethers having â€”COOR end group, wherein R&boxH;H, C1-C10 alkyl, the number average molecular weight of bifunctional and monofunctional perfluoropolyethers being in the range 500-5,000, b) mono, bi or polyfunctional hydrogenated monomers having as functional groups aminic groups, c) polyolefins having functional groups, said polyolefin formed by C2-C4 monomers, said functional groups obtained by grafting with maleic anhydride; reacting in a first step a) with b), or a) with mixtures of monomers b) having a different functionality, until disappearance of the â€”COOR end group of component a), and in a second step reacting the product obtained from the reaction of a) with b) with the functionalized polyolefins c).
