Abstract

Способ получения магнитных полиакриламидных микрогранул диспергированием водной фазы, включающей смесь сомономеров акриламида, магнитный порошок и загуститель, в гидрофобной фазе в присутствии инициатора полимеризации, введением биологически активного вещества, промывкой и сушкой, отличающийся тем, что, с целью интенсификации процесса, в качестве загустителя используют желатину, в качестве гидрофобной фазы - гептан и эмульгатор, а биологически активное вещество вводят в водную фазу перед диспергированием.The method of obtaining magnetic polyacrylamide microgranules by dispersing the aqueous phase comprising a mixture of acrylamide comonomers, magnetic powder and thickener in the hydrophobic phase in the presence of a polymerization initiator, the introduction of biologically active substances, washing and drying, characterized in that, to intensify the process, as a thickener gelatin, as a hydrophobic phase - heptane and an emulsifier, and the biologically active substance is introduced into the aqueous phase before dispersing.
