TECHNOLOGY FOCUS - POLYMERS - Preferred Components:The cyclic non-aromatic units (CNAU) is an optionally substituted 5-, 6-, or 7-membered ring or a combination of these. The CNAU are selected from optionally substituted imidazolinium-, tetrahydropyridinium-, and tetrahydro-1,3-diazepinium groups or a combination of these. The CNAU are located in the polymer main chain and are bonded to it via C- or N atoms. The cationic polymer contains a structural in the main chain of formula (I).R1 = (CH2)n;n = 2,3, or 4;R2 = (CH2)n; andm = greater than 0 and less than 22, CH=CH-CH2-CH2, CH=CH-CH2-CH2, -CH=CH-, CH=CH-CH=CH,a single- or multicore aryl or divalent polyether of formula (Ia):-(CH2)k-(O-(CH2)k)p- (Ia)k = greater than 0 and less than 22;p = greater than 0 and less than 100;R1,R3 = (CH2)l-CH3;l = greater than 0 and less than 21 or a single- or multi-core aryl; andn = 2.In the composition R2 = R1 and the cationic polymer is obtained from linear polyethylene amine. The CNAU are located in the polymer side chains, which have the structures (II) to (VI):u = 2, 3, or 4;R4 = selected from (CH2)r;r = greater than 0 and less than 22;((CH2)s-O-(CH2)s)t,s = greater than 0 and less than 22; andt = greater than 0 and less than 100.CO-Y-(CH2)u,Y = O, NH;u = greater than l and less than 23;R5 = H, CH3, C2H5, C3H7 and can be the same differ inside a unit;R6 = optionally branched 1-18C alkyl and can be the same or differ inside a unit; andR7 = H or R6.The counter ion of the cationic polymer is selected from halide, phosphate, halophosphate, alkyl phosphate, nitrate, sulfate, hydrogensulfate, perfluorinated alkyl- and aryl sulfonates, perchlorate, tetrachloroaluminate, tetrafluopborate, alkyl borate, tosylate, saccharinate, alkyl carboxylate, bis(perfluoroalkylsulfonyl)amide anions and their mixtures.The ionic liquid is a salt with a cation selected from imidazolium-, pyridinium-, ammonium-, and phosphonium ions of structures (VII):R and R' = H, alkyl-, olefin-, or aryl-, or optionally substituted imidazolinium-, tetrahydropyrimidinium-, and tetrahydro-1,3-diazepinium ions.The anion is selected from halide, phosphate, halophosphates, alkyl phosphates, nitrate, sulfate, etc. as above, of a mixture of such salts.
