摘要： Superabsorbents are produced by polymerisation in a kneader equipped with at least two parallel shafts that also comprises elements on at least one shaft that transport the kneader's content parallel to the shafts from a feed section to a discharge section, the process comprising the addition of an inorganic powder to the kneader's contents prior to or during polymerisation and the addition of at least one other additive to the kneader's contents during polymerisation, wherein the inorganic powder is added no later than half the average residence time of the kneader's contents and the other additive is added no earlier than half this residence time.
