Verfahren zur Herstellung von partikelförmigen Homo- und Copolymerisaten aus Mikrosuspensionen in einem Rohrreaktor

摘要

The method used to polymerize a microsuspension enables continuous production of particular homopolymerizates and copolymerizates from at least one polymerizable monomer. The polymerization of the microsuspension, to which addition agents can be added depending on the desired application, is carried out in a tubular reactor at a temperature of at least 0 DEG C C in the presence of a hydrophobic radical polymerization initiator, resulting in particular homopolymerizates and copolymerizates of an average diameter d50 of at least 50 mu m. The polymerizates obtained by this method find applications as addition agents for thermoplastic moulding compounds, as copier toner components, as auxiliary agents for paper and leather, as coating agents for magnetic tapes and foils and as colour and paint components.
