Novel interpolymer complexes of sulfonated octene-1 copolymer

A composition of matter which is a polymer complex which is the reaction product of a sulfonated co- or terpolymer and a basic nitrogen-containing polymer, said basic nitrogen containing polymer having the formula:

• ##STR6## wherein R.sub.1 is H or an alkyl group having about 1 to about 8 carbon atoms, R.sub.2 is an alkyl group having about 1 to about 18 carbon atoms, x is about 50.0 to 99.8 mole percent and y is about 0.2 to about 50.0 mole percent, wherein said sulfonated co- or terpolymer is selected from the group consisting of a sulfonated terpolymer of hexene-1/ethylene/ENB, a sulfonated terpolymer of octene-1/ethylene/ENB, a copolymer of hexene-1/ENB and a copolymer of octene-1/ENB, wherein said sulfonated co- or terpolymer has about 1 to about 40 meq. of metal neutralized sulfonate groups per 100 grams of said sulfonated co-or terpolymer, said sulfonated groups being affixed to said ENB, said metal neutralized sulfonate groups containing a metal ion selected from the group consisting of Groups IA, IIA, zinc, antimony, lead, copper, iron, nickel and cobalt of the Periodic Table of Elements, said basic nitrogen-containing polymer containing about 8 to about 200 meq. of basic nitrogen groups per 100 grams of said basic nitrogen-containing polymer, the weight ratio of said sulfonated co- or terpolymer to said basic nitrogen-containing polymer being about 20/1 to 1/20.
