    Abstract: Preparation of halothio-sulfonamide-modified terpolymers having a low degree of unsaturation is accomplished by preferably reacting N-chlorothio-sulfonamide with an ethylene-(alpha-olefin)-diene monomer terpolymer comprising, for example, 1,4- hexadiene and/or dicyclopentadiene, in the presence of a catalyst of the formula MAn, where A is an anion or mixture of anions of a weak acid, and M is a metal selected from copper, antimony, bismuth and tin and n is a number which corresponds to the oxidation state of M divided by the valence of said weak acid anion. The reaction is preferably carried out in a melt phase process. Additionally, metals such as zinc and iron can be used at low concentrations in a melt phase process or at short reaction times in a solution process. Mixtures of such modified terpolymers with highly unsaturated rubbery polymers and vulcanizates of such mixtures are particularly useful in pneumatic tire sidewalls.
