Following recent advances in free radical polymerization, we developed a controlled route to graft polystyrene on polybutadiene (PB) which overcomes the lack of selectivity of primary free radicals found during the traditional preparation of high impact polystyrene or HIPS.1 In this new approach two stages are included. In the first one, the PB or butadiene copolymers are reacted with diphenylmethyl type stable free radicals 1 to form thermoreversible bonds2,3 and in the second,
