Title (EN) POLYSILOXANE COMPOSITION AND METHOD FOR PRODUCING THE SAME
(FR) COMPOSITION DE POLYSILOXANE ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) A polysiloxane composition containing fine particles of a metal oxide on the surface of which an organosilicon group is present and a method for producing the same are provided. The polysiloxane composition contains a polysiloxane represented by average structural formula (A) and fine particles of a metal oxide on the surface of which an organosilicon group represented by general formula (B) is fixed by means of chemical binding, and a method for producing the aforementioned polysiloxane composition includes reacting fine particles of a metal oxide with an organosilicon compound having a silicon atom-binding hydrolyzable group or a silanol group, and a saturated or unsaturated monovalent organic group in the presence of water under conditions at a temperature of not less than 200°C, to simultaneously form the aforementioned polysiloxane and the aforementioned fine particles of the metal oxide.
(FR) L'invention porte sur une composition de polysiloxane contenant de fines particules d'un oxyde métallique sur la surface desquelles un groupe organosilicium est présent, et sur un procédé de fabrication de ladite composition. La composition de polysiloxane contient un polysiloxane représenté par la formule structurale moyenne (A) et de fines particules d'un oxyde métallique sur la surface desquelles un groupe organosilicium représenté par la formule générale (B) est fixé au moyen d'une liaison chimique, et un procédé de fabrication de la composition de polysiloxane susmentionnée comprend la réaction de fines particules d'un oxyde métallique avec un composé organosilicium ayant un groupe hydrolysable de liaison à un atome de silicium ou un groupe silanol, et un groupe organique monovalent saturé ou insaturé en présence d'eau dans des conditions de température non inférieure à 200°C, pour former simultanément le polysiloxane susmentionné et les fines particules de l'oxyde métallique susmentionnées.
