Abstract: A spin pack for spinning multiple components includes a distribution device which distributes mutually separated molten polymer streams to a spinneret so that each mutually separated molten polymer stream is accessible at each active spinneret backhole. Intermediate the spinneret and the distribution device, a selection assembly selects which, if any, mutually separated molten polymer stream flows into which backhole.

Abstract: The invention relates to a process for the production of a multicoat coating in which an aqueous transparent topcoat composition containing a polyacrylate resin as binder is employed. The polyacrylate resin can be obtained by adding, either successively or alternately in part amounts, a mixture of a carboxyl-containing ethylenically unsaturated monomer (a1) and a monomer (a2) free from carboxyl groups and a mixture (b) consisting of (meth)acrylic acid esters which are free from carboxyl groups, of hydroxyl-containing ethylenically unsaturated monomers and, if appropriate, of other ethylenically unsaturated monomers to an organic solvent and carrying out a polymerization in the presence of a radical-forming initiator and, at the end of the polymerization, neutralizing the resultant polyacrylate resin and dispersing it in water. The type and amount of (a1), (a2) and (b) are chosen so that the polyacrylate resin has a hydroxyl value of 40 to 200, an acid value of 20 to 100 and a glass transition temperature (T.

Abstract: 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.

Abstract: A continuous process for purifying an off-gas which contains CO.sub.2 and HCl and COCl.sub.2. The process comprises passing the off-gas through a separator filled with N,N-dialkylformamide and HCl. This causes a reaction between the COCl.sub.2 and the N,N-dialkylformamide to give the Vilsmeier complex (adduct of COCl.sub.2 and dialkylformamide) and CO.sub.2. The CO.sub.2 leaving the separator contains small amounts of HCl.
