摘要：Process for production of polymer powders containing vinylformamide units viafree-radical polymerization of an aqueous solution of N-vinylformamide and, if
appropriate, other monomers and drying of the polymers, where an aqueous monomersolution which comprises N-vinylformamide and comprises at least one polymerizationinitiator is converted into spray or droplets to give an aerosol at the top of a heatabletower reactor and then the aerosol or the droplets is/are polymerized in an inert gasatmosphere to give a fine-particle solid, and the fine-particle polymer is discharged fromthe reactor.
