Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania koacerwatów na bazie pochodnych chitozanu charakteryzujący tym, że w pierwszym etapie przeprowadza się syntezę dwóch, przeciwnie naładowanych pochodnych chitozanu, a w drugim etapie, poddaje się koacerwacji otrzymane pochodne w środowisku wodnym. Otrzymane koacerwaty wykazywały cechy hydrożelu. Otrzymane koacerwaty można stosować do otoczkowania granul nawozów w złożu fluidalnym.The subject of the application is a method for obtaining coacervates based on chitosan derivatives, characterized by the fact that in the first stage, the synthesis of two, oppositely charged chitosan derivatives is carried out, and in the second stage, the obtained derivatives are coacervated in an aqueous medium. The obtained coacervates showed hydrogel characteristics. The obtained coacervates can be used to coat fertilizer granules in a fluidized bed.
