PROCESS FOR THE SYNTHESIS OF A MAGNETIC COMPOSITE

PROCESS FOR THE SYNTHESIS OF A MAGNETIC COMPOSITE

The invention relates to a process for the synthesis of a magnetic composite meant to be used as a carrier in therapeutic applications. According to the invention, the process consists, in a first stage, in dispersing 3,9-divinyl-2,4,8,10-tetra-oxaspiro [5,5]undecane, in the presence of sodium dodec...

description The invention relates to a process for the synthesis of a magnetic composite meant to be used as a carrier in therapeutic applications. According to the invention, the process consists, in a first stage, in dispersing 3,9-divinyl-2,4,8,10-tetra-oxaspiro [5,5]undecane, in the presence of sodium dodecylbenzene sulphonate, surface active agent, and ferrite as stabilized ferro-fluid in a concentration of 2.8%, under stirring at a temperature of 70°C, in the second stage there being added azo-isobutyronitrile as a radical initiator dispersed in water with 2-hydroxy-ethyl methacrylate or a mixture of 2-hydroxy-ethyl methacrylate and glycidyl methacrylate, the resulting product being then processed and lyophilized, thereby resulting a magnetic composite with an equilibrium swelling degree of 149% and an electric conductivity of 0.584 mS/cm.
