MAGNETISERBARA KOMPOSITMIKROSFAERER I EN HYDROFOBTVAERBUNDEN POLYMER, DERAS FRAMSTAELLNINGSFOERFARANDE OCH ANPASSANDE I BIOLOGI. |
摘要 |
Magnetisable microspheres from 0.05 to 10 mu m in diameter, comprising a core of magnetisable particles and a skin consisting of a hydrophobic crosslinked copolymer derived from a vinylaromatic monomer and from a crosslinking emulsifying polymer. They are obtained by preemulsifying in water a magnetic liquid made up of magnetisable particles dispersed in a vinylaromatic monomer and in a crosslinking emulsifying polymer, polymerisation, separation of the magnetisable microspheres and optional redispersion in water. Use in biology. <IMAGE> |
