Method for producing polymers in micro-fine form, in particular factice, preferably on the basis of sustainable raw materials

摘要

Producing polymers, preferably factice based on natural oils, which is peroxidically crosslinked in micro-fine form by grinding, comprises (i) providing a dispersion comprising factice-powder as peroxide crosslinked polymer and a liquid medium comprising paint solvent, preferably butyl acetate, where the dispersion has solids content of less than 75 wt.%, preferably 30 wt.%, and (ii) homogenizing in at least one homogenizer (4) with respective upstream nozzle (3) under repeated implementation by the homogenizer under pressure, preferably 4-800 bars. Producing polymers, preferably factice based on natural oils, which is peroxidically crosslinked in micro-fine form by grinding, comprises (i) providing a dispersion comprising factice-powder as peroxide crosslinked polymer and a liquid medium comprising paint solvent, preferably butyl acetate, where the dispersion has solids content of less than 75 wt.%, preferably 30 wt.%, and the factice- powder has an average grain size of less than 100 mu m, preferably less than 80 mu m, and (ii) homogenizing in at least one homogenizer (4) with respective upstream nozzle (3) under repeated implementation by the homogenizer under pressure, preferably 4-800 bars. An independent claim is also included for a paint comprising factice.
