    Abstract: The invention relates to a method for operating a kneader-mixer (1) comprising one or more shafts (2, 3) provided with kneading bars (4) on the surfaces thereof and which are surrounded by a covering (6). Said method comprises the following steps: • (a) introducing starting material to a supply point (10) of the kneader mixer (1), • (b) reacting the starting material in an exothermic reaction, a continuously kneadable intermediate product being initially formed during the reaction • (c) tearing and comminuting the continuously kneadable intermediate product in order to form a product, the exothermic reaction optionally continuing during the tearing and comminuting, • (d) extracting the product at an extraction point (11) of the kneader mixer, at least one of the shafts (2, 3) and/or the covering being heated, when the kneader-mixer is in operation, to a temperature higher than 20 °C.

    Abstract: The invention relates to an apparatus for production of pulverulent poly(meth)acrylate, comprising a reactor (1) for droplet polymerization having an apparatus for dropletization (5) of a monomer solution for the production of the poly(meth)acrylate having holes through which the solution is dropletized, an addition point for a gas (13) above the apparatus for dropletization (5), at least one gas withdrawal point (19) on the circumference of the reactor (1) and a fluidized bed (11). The outermost holes through which the solution is dropletized are positioned in such a way that a droplet falling vertically downward falls into the fluidized bed (11), and the hydraulic diameter at the level of the midpoint between the apparatus for dropletization (5) and the gas withdrawal point (19) is at least 10% greater than the hydraulic diameter of the fluidized bed (11).
