(i) 100 pts. wt. of a polyimide of formula (I); and (ii) 5-100 pts. wt. of a fluororesin (II). In (I), Y = a bond, divalent C1-10 hydrocarbon, hexafluorinated isopropylidene, carbonyl, thio, sulphinyl, sulphonyl and oxide; R= tetravalent radicals selected from 2 or more C aliphatic, alicyclic, monoaromatic, condensed polyaromatic and non- condensed polyaromatic radicals in which the aromatic radicals are mutually connected with a bond or crosslinking function. (II) is elected from PTFF, TFE- hexafluoropropylene copolymer, TFE-TFEperfluoroalkyl vinyl ether copolymer, ethylene-TFE copolymer, ethylene chlorotrifluoroethylene copolymer and polyvinylidene fluoride.
