Abstract

Process for continuous manufacture of block copolymer in the form of impact-resistant transparent vinylaromatic resin or of vinylaromatic block elastomer, consisting in: a) polymerising a vinylaromatic polymer in concentrated medium, b) then copolymerising the living polymer with a conjugated diene, still in concentrated medium c) then coupling the copolymer. f
