Abstract (en)
[origin: WO2004039855A1] The invention relates to an anionic polymerisation method for producing impact-resistant polystyrene, according to which 1) a rubber solution is produced from diene monomers or diene and styrene monomers by anionic solvent polymerisation using lithium organyl, 2) aluminium organyl is added until the molar ratio Al/Li > 1, (or > 0.5 for dialkylaluminium phenolates), 3) a styrene monomer is added, 4) lithium organyl or lithium organyl and aluminium organyl is/are added until the molar ratio Al/Li < 1, (or < 0.5 for dialkylaluminium phenolates) and the mixture is then polymerised.
