摘要

MICROSPHERES COMPOSITAS magnetizable FORMED OF A CORE OF LOADS magnetizable DISTRIBUTED UNIFORMLY IN A NETWORK OF A polysilsesquioxane (SIVI) having unsaturated ethylenic and a shell of a polymer ORGANOSILICEADO RETICULATED DERIVATIVE hydrosilylation A ORGANOHIDROGENOPOLISIXANO SIH WITH GROUPS ETILEMICAMENTE NO SATURATED THE polysilsesquioxane SIVI . They OBTAINED BY DISPERSION in a solvent of aqueous Slurry magnetizable Uncoated dispersing agent, dissolving an alkoxysilane OR AN alkoxysiloxane PRESENTING unsaturations ETILEMICAS, polycondensation A polysilsesquioxane SIVI, removing water, dissolution in the organic phase of POLYMER SIH, reticulation, water removal, removal of microspheres and redispersion EVENTUALLY IN WATER. USE AS ACTIVE SUPPORT IN BIOLOGY.
