Abstract
1421209 Perfluoropolyether polyamides MONTECATINI EDISON SpA 26 April 1973 [26 April 1972] 19884/73 Heading C3R An elastomeric perfluoropolyether polyamide comprises units (U) where units -CF 2 O- and -C 2 F 4 O- are randomly distributed; n and m are each 2-100, n+m is 5-200, and m/n is 0À2-1À5; R is H, alkyl, or phenyl; and A is (a) a C 2-20 aliphatic hydrocarbon radical, (b) an alicyclic hydrocarbon radical with a C 5-10 ring, (c) an aromatic heterocyclic radical with a C 5-6 ring, (d) an aromatic or alkylaromatic hydrocarbon or chlorinated hydrocarbon radical, or (e) a radical comprising two or more substituted or unsubstituted benzene rings linked directly or through an -NH-, -CO-, -SO-, -SO 2 -, alkylene, or vinyl group. The polydispersivity index may be 1À0-1À3. The polyamide may also contain up to 30% by number, with respect to unit (U), of recurring units (V) containing additional functional group(s) that provide reactive points for cross-linking, these groups being, e.g. a double-bond, or -COOH, -SO 3 H, -OH, or amino or alkylamino. These units (V) may be derived from an ester of fumaric acid, or 3,5- diaminobenzoic, 3,5-diaminobenzenesulphoric, pyromellitic, benzophenone tetracarboxylic, trimellitic, or cyclohexenylenedicarboxylic acid, or 1,3,5-benzenetriamine or 4,4
