ABSTRACT OF THE DISCLOSURE Novel functional ionene polymer compositions have been prepared which have been found to be useful in a wide variety of applications, including, among other, as wet and dry strength additives, corrosion inhibitors, and electroconductive coatings, and which comprise recurring units of the formula: Image wherein R represents the group CH2 and/or a substituted CH2 group where one of the hydrogen atoms of the group is replaced by alkyl or hydroxymethyl; wherein Y is a member selected from the groups consisting of Image , Image , -C ? C- , -O- , Image , Image , -OCH2CH2O- , Image , -OCH2O- , -S- , -SO- , -SO2- , and aryl; wherein R1 represents the group: Image where R3 is hydrogen, halogen, alkyl, cycloalkyl, aryl, alkaryl, or aralkyl; and where R4 is a member selected from the group consisting of: -C ? N, Image , Image , Image , Image , Image where R3 has the same meaning as above; where R5 is selected from the group consisting of alkyl, cycloalkyl and alkoxyalkyl; where R6 has the same meaning as R5, additionally including aryl; where R7 and R8 are each independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, aryl, alkaryl, aralkyl, and alkoxyalkyl; wherein P2 is a straight or branched alkyl chain of 1 to 18 carbon atoms, which may be interrupted by one or more atoms of oxygen or sulfur; aralkyl or cycloalkyl; wherein ?? is an anion; and wherein x and y are integers from 1 to 10.
