POLYMER-COATED FINE INORGANIC PARTICLE AND PROCESS FOR PRODUCING THE SAME
摘要
<p>An object of the present invention is to provide a polymer coated magnetic fine polymer by coating an inorganic fine particle with a thin polymer layer under precise control of a polymerization reaction and a method for preparing the same. Onto a surface of the inorganic fine particle the iniferter is fixed and grafted chains are formed on the inorganic fine particle by a living radical polymerization using the iniferter as an initiator which is defined by the following chemical formula:
(wherein X is a hydrophilic atomic group being capable of binding to a surface of the inorganic fine particle, R1 and R2 are each independently selected from a mono-valent hydrocarbyl group which is formed by removing one hydrogen atom from hydrocarbon.)</p>
