Magnetic particles for diagnostics |
摘要 |
The organic polymer particles comprise a carboxyl group and 2,3-dihydroxypropyl group, and the magnetic particles for diagnostics comprise fine magnetic material particles and a polymer part containing a hydrophilic polymer part and a crosslinked polymer part, a dry coating film obtained from a water dispersion thereof having a contact angle with water of 5° to 60°. The process for producing the carboxyl group-containing particles comprises a step of producing an ester bond by reacting a hydroxyl group in organic polymer particles having the hydroxyl group with a carboxylic anhydride. The organic polymer particles comprise a hydroxyl group originating from a 2,3-dihydroxypropyl group and a polyoxyethylene group. |
