摘要： A process is described for preparing styrene polymers by continuous anionic polymerization, the monomer or monomers and the organometallic compound serving as starter (initiator) being added in solution to a tubular reactor operating essentially without backmixing and being left in the reactor until the monomer has been consumed, wherein the polymerization is carried out in at least two successive tubular reactor sections operating in each case essentially adiabatically, with in each case at least one heat exchanger arranged between the sections. If desired a proportion of the starter and/or of the monomer is added to at least one reactor connected downstream of the first reactor.
