    摘要: A process for the preparation of vinylaromatic (co)polymers grafted on an elastomer comprising a rigid matrix consisting of vinylaromatic polymers or copolymers and of an elastomeric phase dispersed in the matrix in form of particles with a strictly bimodal distribution which comprises the functionalization of a first elastomeric fraction by means of a catalytic system containing a stable free radical initiator and subsequently the polymerization of the thus obtained mixture also in presence of a second non functionalized elastomeric fraction.

    摘要: A process for the preparation of vinylaromatic (co)polymers grafted on an elastomer in a controlled way, comprising the dissolving of an elastomer, such as polibutadiene, in a mixture consisting of a monomer and of a solvent in the presence of a polymerization catalytic system, which comprises an initiator of free radicals and a stable initiator of free radicals. The mixture obtained in this way is heated to a temperature of about 100° C. to functionalize the rubber, then more monomer is added and the temperature is raised to start the polymerization reaction.
