PROCESS FOR PRODUCING FINE ORGANOMETALLIC PARTICLES AND CATALYST FOR POLYMERIZATION |
摘要 |
<p>The present invention provides: a production process for a polyalkylene oxide with fast polymerization reaction rate and good production efficiency; a catalyst for polymerization and a dispersion thereof which are effective for the above production process for a polymer such as polyalkylene oxide; and an organometallic fine particle and a production process therefor, which particle is, for example, useful as the above catalyst for polymerization. In a means therefor, a material such as an aliphatic polyol is reacted upon an organometallic compound in a micelle as the reaction field, thus preparing a hyperfine particle, which is used as a catalyst for polymerization of ionic-polymerizable monomers mainly including a cyclic ether.</p> |
