Abstract: A continuous anionic polymerisation or copolymerisation process of styrene or diene monomers with alkali metal alkyl as polymerisation initiator is carried out in the presence of a metal alkyl or aryl of an at least bivalent element as reaction speed regulator, preferably in non-isotherm conditions and without a back admixture in a pipe or pipe bundle reactor. A metal alkyl or aryl A of formula R M and a metal alkyl or aryl B of formula R nM in a molar ratio between B and A from 0.1:1 to 500:1 are used. In the formulas, M is Li, Na or K; R is hydrogen, C1-C20-alkyl or C6-C20-aryl or C7-C20-alkyl-substituted aryl; M is an n-valent element of groups 2a, 2b or 3a of the periodic table of elements; and R is hydrogen, halogen, C1-C20-alkyl or C6-C20-alkyl. Also disclosed is a special initiator for the anionic polymerisation which does not contain any Lewis bases. 00000

Abstract: A process for the continuous anionic polymerization or copolymerization of styrene or diene monomers using an alkali metal alkyl compound as polymerization initiator is carried out in the presence of an alkyl- or arylmetal compound of an element which occurs in at least divalent form as rate regulator, preferably under non-isothermal conditions and without back-mixing in a tubular or tube-bundle reactor, preferably using an alkyl- or arylmetal compound A of the formula R1M1 and an alkyl- or arylmetal compound B of the formula R2nM2 in a molar ratio between B and A of from 0.1:1 to 500:1, whereM1 is Li, Na or K;R1 is hydrogen, C1-C20-alkyl, C6-C20-aryl, or C7-C20-alkyl-substituted aryl;M2 is an n-valent element from group 2a, 2b or 3a of the Periodic Table; andR2 is hydrogen, halogen, C1-C20-alkyl or C6-C20-aryl; and a special anionic polymerization initiator containing no Lewis base.

Abstract: The anionic polymerization of dienes or copolymers of dienes and vinylaromatic monomers in a vinylaromatic monomer or monomer mixture to give homopolydienes or copolymers or mixed homopolydienes and copolymers is carried out in the presence of a metal alkyl or aryl of an element having a valence of at least two without addition of Lewis bases.
