摘要：
Process for the preparation of vinyl aromatic (co) polymers grafted on an elastomer in a controlled manner, comprising: dissolving an elastomer functionalized with bromoalkanes and nitroxy radicals, soluble in non-polar solvents, in a liquid phase consisting of a mixture of vinyl aromatic monomer(s)/polymerization solvent; feeding at least one radical initiator to the mixture, containing the functionalized elastomer in solution, and polymerizing the mixture thus obtained at a temperature higher than or equal to 1200 C; recovering the vinyl aromatic (co) polymer obtained after devolatization; and recycling the solvent/monomer(s) mixture, coming from the devolatization, to step (a).
