Abstract
Process for the manufacture of impact-resistant vinylaromatic resin by radical polymerisation in an inert solvent medium of a vinylaromatic monomer in the presence of a polybutadiene, characterised in that butadiene is polymerised anionically in a solvent which is inert towards butadiene and the vinylaromatic monomer and then, after destruction of the anionic catalyst, the radical polymerisation is initiated after addition of vinylaromatic monomer to the mixture.
