20090050852 | Metal Oxide Particle-Containing Polysiloxane Composition and Method for Producing Same - The metal oxide fine particle-containing polysiloxane composition of the present invention is obtained by mixing (A) metal oxide fine particles with (B1) polyfunctional polysiloxane obtained by allowing alkoxy-terminated polyfunctional polysiloxane (b1) represented by the following average compositional formula (1): R | 02-26-2009 |
20090093579 | OXIDE PARTICLE-CONTAINING POLYSILOXANE COMPOSITION AND METHOD FOR PRODUCING SAME - The oxide fine particle-containing polysiloxane composition of the present invention is obtained by mixing (A) silicon oxide fine particles and/or metal oxide fine particles with (B) polyfunctional polysiloxane in an organic solvent in the presence of a basic compound, an acidic compound or a metal chelate compound and thereby dispersing the oxide fine particles (A) in the organic solvent. In the oxide fine particle-containing polysiloxane composition, the oxide fine particles are highly dispersed in the organic solvent without using phosphoric acid or the like having an organic group of 6 or more carbon atoms or a compound having an oxyalkylene group. A polysiloxane-based cured product obtained from such an oxide fine particle-containing polysiloxane composition has excellent transparency and is hardly yellowed even at high temperatures. | 04-09-2009 |
