ABSTRACT:
This invention relates to improved polymeric compositions of metal, amine and ammonium neutralized sulfonated polymers which are preferentially plasticized with an N-substituted organic carbamate at a minimum critical concentration level of at least 1 part by weight based on 100 parts by weight of the neutralized polymer, wherein N-substituted organic carbamate has the general formula selected from the group of: ##STR1## wherein R.sub.1, and R.sub.2 are normal or branched chain alkyl, cycloalkyl, aryl, alkaryl, or arylalkyl groups such as ethyl, butyl, octadecyl, behenyl, phenyl, benzyl, and dodecylphenyl and R.sub.4 and R.sub.6 and either R.sub.1 or R.sub.2 must be a long chain, preferably linear, saturated group containing from about 10 to about 50 carbon atoms and R.sub.3 and R.sub.5 are di, tri, or tetrafunctional aliphatic, cycloaliphatic, aryl or alkaryl groups and m is 2, 3, or 4 and n is 2, 3 or 4.
