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 rubber elastic block copolymer has at least one block A made of polymerise d units of a vinyl aromatic monomer that forms a hard phase and/or a block B with diene monomers that forms a first rubber elastic (soft) phase, and at least one elastomer block B/A with polymerised units of both a vinyl aromatic monomer and a diene that for ms if required a second or additional soft phase. The glass transition temperature T g of block A is higher than 25 .degree.C and that o f blocks B or B/A is lower than 25 .degree.C. The phase volume ratio between blocks A and B/A is selected so that the hard phase represents 1 - 40 % by volume of the total block copolymer and the diene amounts to less than 50 % by weight.
