Abstract: Countercurrent stripping pipe for removing volatile organic constituents from reaction products, having a column pipe ( 201 ) composed of a plurality of pipe sections ( 201 a-d), in which trays ( 202 ) are arranged, connections ( 205, 208 ) for supplying and removing the reaction products and connections ( 206, 207 ) for supplying and removing at least one stripping agent in countercurrent to the reaction products. In accordance with the invention, a plurality of successive trays ( 202 ) in each case are joined to one another and form at least two inserts ( 211 a-c) which can be removed from the column pipe ( 201 ).

Abstract: A process for the production of low-viscosity, aqueous polymer dispersions (APD), with polymer concentrations of at least 50 vol% and viscosities of less than 1000 mPa.s, comprises radical emulsion polymerisation of ethylenic monomers (except vinyl and vinylidene halides), by the monomer addition method, in the presence of an initiator and small amounts of water-miscible organic solvent(s) (I). Also claimed are APD obtained by this process.

Abstract: Production of aqueous polymer dispersions with low viscosity and a polymer volume concentration NOTLESS 50 vol.% comprises free radical emulsion polymerisation of ethylenically unsaturated monomers, except vinylidene halides, in the presence of initiator(s) and a starting polymer. Most of the monomers are emulsified in an aqueous dispersion of the starting polymer and this emulsion is transferred continuously to the polymerisation reaction.
