Abstract: The invention relates to the use of an apparatus for adding at least one solid or viscous liquid additive, or an additive dispersed in solvent, to a reactor interior of a reactor for preparing crosslinked, finely divided polymers by copolymerizing (a) water-soluble, monoethylenically unsaturated monomers and (b) from 0.001 to 5 mol %, based on the monomers (a), of monomers comprising at least two polymerizable groups, (c) from 0 to 20 mol %, based on the monomers (a), of water-insoluble monoethylenically unsaturated monomers, where the apparatus comprises at least one screw for conveying the at least one additive and the at least one screw ends in an addition orifice substantially flush with the inner wall of the reactor interior.

Abstract: Mixing kneader comprises at least two shafts (2, 3) that bear kneading bars (5) on crosspieces (4), can rotate in bearings at both ends, are driven from at least one end and are surrounded by a housing (6) that has top openings (10) above the shafts and a product discharge opening (11). The mixing kneader has at least one of four defined features, e.g. the natural bending frequencies of the shafts differ from the excitation frequencies by at least 5%. Mixing kneader comprises at least two shafts (2, 3) that bear kneading bars (5) on crosspieces (4), can rotate in bearings at both ends, are driven from at least one end and are surrounded by a housing (6) that has top openings (10) above the shafts and a product discharge opening (11). The mixing kneader has at least one of the following features: the natural bending frequencies of the shafts differ from the excitation frequencies by at least 5%; at least one shaft is a hollow shaft through which a temperature-controlling medium flows from an inlet (12) to an outlet (13); at least one top opening is closed by a displacer and the gap between the displacer and the kneading bars is no greater than that between the kneading bars and the housing; the cross-section of the product discharge opening is adjustable. An independent claim is also included for a process for producing poly(meth)acrylates using a mixing kneader as above.
