  The present invention relates to a method for preparing poly(organic oxidized silicon) particles having UV-absorbing groups, including reacting an organoalkoxysilane precursor having a UV-absorbing group selected from a group consisting of organotrialkoxysilane, diorganoalkoxysilane and a mixture thereof, in the presence of a base, with a silane compound selected from a group consisting of tetraalkoxysilane, alkyltrialkoxysilane, tetraalkoxysilane, aryltrialkoxysilane, dialkyldialkoxysilane, diaryldialkoxysilane, arylalkyldialkoxysilane and a mixture thereof, serving as a crosslinking regulator and UV stability enhancer, so as to prepare poly(organic oxidized silicon) particles selected from a group consisting of polysilsesquioxane, silsesquioxane-siloxane copolymer, silsesquioxane-silica copolymer, silsesquioxane-siloxane-silica copolymer and silsesquioxane-siloxane copolymer, having UV-absorbing groups. The poly(organic oxidized silicon) particles significantly solves the problem of poor UV stability, while maintaining UV absorption by the UV-absorbing group contained in the particles. Since the poly(organic oxidized silicon) particles having UV-absorbing groups do not exhibit white turbidity, they can be effectively used in cosmetics. In accordance with the present invention, the poly(organic oxidized silicon) particles having UV-absorbing groups can be prepared economically as compared to the existing methods.

  本发明涉及一种制备具有UV吸收基团的聚（有机氧化硅）颗粒的方法，包括在碱的存在下，通过将具有从有机三烷氧基硅烷、二有机烷氧基硅烷和二者的混合物中选择的UV吸收基团的有机烷氧基硅烷前体与从四烷氧基硅烷、烷基三烷氧基硅烷、四烷氧基硅烷、芳基三烷氧基硅烷、二烷基二烷氧基硅烷、二芳基二烷氧基硅烷、芳基烷基二烷氧基硅烷和二者的混合物中选择的硅烷化合物反应，作为交联调节剂和UV稳定性增强剂，制备具有UV吸收基团的聚（有机氧化硅）颗粒，所述聚（有机氧化硅）颗粒选自聚硅倍半氧烷、硅倍半氧烷-硅氧烷共聚物、硅倍半氧烷-二氧化硅共聚物、硅倍半氧烷-硅氧烷-二氧化硅共聚物和硅倍半氧烷-硅氧烷共聚物，具有UV吸收基团。这些具有UV吸收基团的聚（有机氧化硅）颗粒显著解决了UV稳定性差的问题，同时保持了颗粒中所含UV吸收基团的UV吸收性。由于这些具有UV吸收基团的聚（有机氧化硅）颗粒不会呈现白色混浊，因此可以有效用于化妆品。根据本发明，与现有方法相比，具有UV吸收基团的聚（有机氧化硅）颗粒可以经济地制备。
