Abstract: Initiator systems for anionic polymerization of vinyl monomers with polar groups, containing A) a1) at least one starter having general formula R -M or R -M -RC, wherein R , R or R independently stand for branched or straight-chain alkyl radicals of 1-6 carbon atoms, aryl radicals of 6-20 carbon atoms or alkyl radicals with 1-6 carbon atoms carrying at least one phenyl radical and M stands for a metal selected from the group of alkaline metals, and M stands for a metal selected from the group of alkaline earth metals, or a2) as a starter "living" polymer chains, whose chain ends are possibly stabilized by sterically demanding and/or aromatic radicals and B) at least one alkaline (I) or alkaline earth metal alcoholate (II) or at least one alkaline (I) and at least one alkaline earth metal alcoholate (II) which have at least one amino or one phosphino substituent or at least one amino and one phosphino substituent.

Abstract: Solvent-free diene rubber solutions prepared continuously in a spray tower reactor with an inner wall by polymerization of monomers with insertion of an anionic initiator, and deposition of the diene rubber particles on the reactor inner wall without repulsion by this wall are new. An Independent claim is included for an apparatus for preparing the solvent free solutions comprising a spray tower reactor, a wall and a second wall (1b) with openings arranged so that an inner space is formed between the reactor inner wall and the second wall (1b).

Abstract: A process is disclosed for continuously producing expandable styrene polymers by polymerising styrene in the presence of expanding agents in three steps: (a) prepolymerising styrene in the mass; (b) dispersing the prepolymer in an aqueous phase; and (c) polymerising the prepolymer in an aqueous suspension.
