Plasticisation of neutralised sulphonated polymer with organic carbamate.

摘要

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: wherein R1, and R2 are normal or branched chain alkyl, cycloalkyl, aryl, alkaryl, or arylalkyl groups such as ethyl, butyl, octadecyl, behenyl, phenyl, benzyl, and dodecylphenyl and R4 and R6 and either R1 or R2 must be a long chain, preferably linear, saturated group containing from about 10 to about 50 carbon atoms and R3 and R5 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.
