  • Method for producing polymer particles by the polymerization of fluid drops in a gas phase
    Patent number: 8114320
    Abstract: A process for producing polymer particles by polymerizing liquid droplets in a gas phase by metering a liquid comprising at least one monomer from at least one feed by means of a multitude of bores into a reaction chamber comprising the gas phase, wherein ratio of length of the feed to greatest diameter of the feed in the region of the multitude of bores is at least 10.
    Type: Grant

  • Dropping method for liquids
    Patent number: 7994266
    Abstract: In a process for dropletizing a liquid by means of a dropletizer plate at least the underside of the dropletizer plate has at least in part a contact angle of at least 60° with regard to the liquid to be dropletized.

  • Process for Preparing Superabsorbents
    Publication number: 20110001087
    Abstract: 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.
