  • Use of an apparatus for adding at least one additive to a receptor interior
    Patent number: 8790003
    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.

  • Method for producing dyed moulding materials
    Patent number: 6329448
    Abstract: A continuous process for preparing pigmented thermoplastic molding compositions in an extruder, comprises I) in a first zone A) metering in from 10 to 99.999% by weight of a thermoplastic polymer into an extruder and II) in a subsequent zone at temperatures below the respective glass transition temperature of the thermoplastic A) B) adding from 0.001 to 60% by weight of a colorant and then heating the thermoplastic/colorant mixture in the subsequent zones, homogenizing the polymer melt and extruding the resultant mixture.
