ABSTRACT:
Crude graft products of styrene on polyolefinic rubbers in which, in the gel, the polystyrene/polyolefinic rubber ratio is shifted to relatively high polystyrene contents, always higher than 1:1, and which graft products are characterized by a satisfactory, which is to say commercially acceptable, distribution of the rubber particles in the polystyrene matrix are obtained by subjecting a solution of a polyolefinic rubber or elastomer in styrene to polymerizing conditions in aqueous phase in the presence of a radical initiator and of a chain transfer agent.
