MAGNETISERBARE ORGANOPOLYSILOXAN-BASEREDE MIKROKUGLER TIL BIOLOGISK ANVENDELSE OG FREMGANGSMAADE TIL FREMSTILLING AF SAADANNE MIKROKUGLER

摘要

Magnetisable microspheres, as they are or in aqueous dispersions, consisting of a matrix of at least one organopolysiloxane optionally bearing Si-vinyl groups or reactive and/or ionogenic units and, encapsulated in said matrix, magnetisable particles less than 300  ANGSTROM in size. …They are prepared by homogenisation of a solution of the said organopolysiloxane and a magnetic fluid in the presence of water and a surfactant, removal of the solvent of the organopolysiloxane and of the carrier liquid of the magnetic fluid and at least partial removal of the water. …They may be used in biology.
