    • A modified polyaluminosiloxane obtained by treating a polyaluminosiloxane with a silane coupling agent represented by the formula (I): wherein each of R1, R2 and R3 is independently an alkyl group or an alkoxy group; X is a methacryloxy group, a glycidoxy group, an amino group, a vinyl group or a mercapto group, with proviso that at least two of R1, R2 and R3 are alkoxy groups. The photosemiconductor element encapsulating material of the present invention is suitably used for, for example, photosemiconductor devices mounted with blue or white LED elements (backlights for liquid crystal displays, traffic lights, outdoor big displays, advertisement sign boards, and the like).
    • 通过用式(I)表示的硅烷偶联剂处理聚铝硅氧烷获得的改性聚铝硅氧烷:其中R1,R2和R3各自独立地为烷基或烷氧基; X是甲基丙烯酰氧基,缩水甘油氧基,氨基,乙烯基或巯基,条件是R 1,R 2和R 3中的至少两个是烷氧基。 本发明的光半导体元件封装材料适合用于例如安装有蓝色或白色LED元件的光半导体器件(液晶显示器的背光灯,交通灯,户外大显示器,广告牌等)。
