MICROESFERAS COMPOSITAS MAGNETIZAVEIS A BASE DE UM POLIMERO DE ORGANOSILICIO RETICULADO, PROCESSO PARA A SUA PREPARACAO E SUA APLICACAO EM BIOLOGIA |
摘要 |
Magnetisable composite microspheres made up of a core consisting of magnetisable fillers distributed uniformly in a lattice of a polysilsesquioxane (SiVi) containing ethylenic unsaturations and a skin made of a crosslinked organosilicon polymer derived from the hydrosilylation of an organohydropolysiloxane (SiH) with the ethylenically unsaturated groups of the polysilsesquioxane SiVi. …<??>They are obtained by dispersion in a solvent of an aqueous suspension of magnetisable fillers not coated with dispersing agent, dissolving of an alkoxysilane or of an alkoxysiloxane containing ethylenic unsaturations, polycondensation to a polysilsesquioxane SiVi, removal of water, dissolving of the SiH polymer in the organic phase, crosslinking, removal of water, isolation of the microspheres and optionally redispersion in water. …<??>Use as active support in biology. |
