PROCEDE POUR PROTEGER CONTRE LA CORROSION ET/OU PREPARER A LA MISE EN FORME UNE PIECE METALLIQUE

摘要

A method comprising the use of a non-cross-linked block or graft copolymer film having a thickness of 0.5-5 mu m and including at least one "polar" block (ii) and at least one "apolar" block (i). The solubility parameters of the monomeric units of the apolar block (i) are all no higher than 19.1 J<1/2>.cm<-3/2>, and at least one of the monomeric units of the polar block (ii) is non-ionic, has a solubility parameter higher than 19.1 J<1/2>.cm<-3/2>, and constitutes at least 5 wt.% of said copolymer.
