Abstract: Continuous radical bulk polymerisation of vinyl monomers opt. contg. small amts. of solvent and/or initiator is such that: (a) the starting mixt. is fed to a stirred or circulating reactor (2) where it is converted to a polymer content of 45-65 (esp. 50-60) wt.% before being passed to an adiabatically operated tubular reactor (5) in which an approx. plug flow dominates, the polymer content being increased to 65-90 (esp. 70-85) wt.% in this reactor (5), with the monomer fraction at outlet (6) being at least 10 wt.%; and (b) the polymer prodn. in stirred reactor (2) is at least 1.5 times that in tubular reactor (5) and the polymer soln. leaving reactor (5) is degassed without further reaction. ADVANTAGE - Monomers such as styrene can be polymerised to high conversions with a high space-time yield.

Abstract: A process for the preparation of block copolymers of styrene or equivalents thereof on the one hand and of butadiene or equivalents thereof on the other hand by sequential anionic polymerisation, in which firstly one first monomer and the organometallic compound serving as initiator are combined to form a reaction mixture, and the reaction is continued until at least some of the first monomer has been consumed and at least one further monomer is then added and in each case reacted partly or fully, characterised in that the polymerisation is carried out continuously in a manner known per se in a tubular reactor, where the reaction of one monomer in each case is carried out in one reactor section (zone) in each case, and at least two reactor sections are separated by a mixing zone.
