摘要 |
The invention relates to a method of polymerizing dienes in a solvent that contains vinyl-aromatic monomers. Said polymerization is carried out in the presence of an organometallic compound of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo or W as the catalyst and a Lewis acid as the cocatalyst and optionally an alkylating agent and optionally a controlling agent. The invention further relates to a method of producing impact-resistant polystyrene, acrylnitril-butadiene-styrene polymers or methylmethacrylate-butadiene-styrene copolymers. |
