Thermoplastic rubber compositions comprising
a) an at least partly neutralized carboxylated elastomeric polymer, wherein
1) the polymer is substantially free of olefinic unsaturation,
2) the carboxyl groups originate in the in the reaction of the non-carboxylated elastomeric polymer with at least 0.5 pbw of an azido-sulfonylbenzoic acid per 100 pbw of polymer
3) a metal-based neutralizing agent has been used for the neutralization of the carboxyl groups, and
4) the degree of neutralization of the carboxyl groups is at least 50%,
and
b) a zinc carboxylate, based on a linear or branched monocarboxylic acid having at least 12 carbon atoms per molecule, which zinc carboxylate is present in an amount of at least 6 pbw per 100 pbw of said carboxylated polymer.
