Polyheterocyclic polymers derived from substituted tetraamino pyridines

Claim 1

Polymers consisting essentially of recurring units of the following structural formula: ##STR48## wherein R 1 represents a monovalent member selected from the group consisting of alkyl, substituted alkyl, alkenyl, substituted alkenyl, arylalkyl, aryl, heteroaryl, heteroarylalkyl, substituted arylalkyl, substituted aryl and substituted heteroaryl, with aryl and heteroaryl including monocyclic, linear bicyclic and fused ring structures; wherein the substituents on said members are selected from the group consisting of methyl, phenyl, pyridyl, --CN, --COOH and salts thereof, ##STR49## --COOC 6 H 5 , --SO 3 H and salts thereof, --SH, thioaryl, --CH═CHC 6 H 5 and N,N-dimethylamino; R 2 represents a monovalent radical selected from the group consisting of hydrogen, methyl, ethyl, propyl, butyl and pentyl; and R 4 represents a divalent radical selected from the group consisting of paraffinic, cycloparaffinic, perfluoroalkyl, perfluoropolyalkylene oxide, alkenyl, carbocyclic, heterocyclic, and inorganic/organic radicals, said cyclic radicals having a single, multiple or fused ring structure, the multiple ring structures including polyarylenes with 2 to 9 aryl rings in which the aryl groups are bonded directly to each other or bridged by a divalent member selected from the group consisting of alkylene with up to 3 carbon atoms, perfluoroalkylene of 2 to 10 carbon atoms, ##STR50## membered heterocyclics containing at least one nitrogen atom, and mixtures thereof, and substituted aromatic or heterocyclic radicals where the substituents are selected from lower alkyl, phenyl, F, Cl, --CN, --SO 3 H, and ##STR51## with the proviso that the --CN, --SO 3 H or ##STR52## groups are not ortho or peri to a ##STR53## group bonded to R 4 ; said inorganic/organic radicals being selected from the group consisting of ferrocenyl, carboranyl, and biaryls separated by at least one phosphorus atom or by at least one silanyl or siloxanyl group, and mixtures thereof; with the proviso that R 4 is a divalent radical or substituted divalent radical of formula ##STR54## where Z is selected from the group consisting of H, CH 3 , and ##STR55## and the Z groups are not required to be identical and are located 1,2 or 1,3 to a ##STR56## group bonded to R 4 when R 4 is alkylene or cycloalkylene but located ortho or peri to said ##STR57## group when R 4 is arylene or heterocyclic, with the proviso that both Z groups are not ortho to the same ##STR58## group when the Z groups are ##STR59## when R 4 is perfluoropolyalkylene oxide or carboranyl the ##STR60## counterpart does not exist; R 5 is H or alkyl of 1 to 5 carbon atoms, R 6 represents H, lower alkyl, or phenyl; the symbol → denotes possible isomerism; each of all the R 1 's, R 2 's and R 4 's need not be identical; and the acid salts thereof, the acid of said salts being selected from the group consisting of HCl, HBr, H 3 PO 4 , CH 3 SO 3 H, CF 3 SO 3 H, CF 3 COOH and mixtures of said salts.
