    • The composition for optical materials includes a polymer obtained from silsesquioxanes which are represented by average composition formula (1): (R1SiO1.5)x(R2SiO1.5)y (wherein R1 is a polymerizable group, R2 is a non-polymerizable group, x is a number of 2.0 to 14.0, y is a number of 2.0 to 14.0, provided that x+y=8.0 to 16.0, and R1 groups and R2 groups may be the same or different) and include at least one cage silsesquioxane compound. This composition is suitable for use as the antireflective film in optical devices, has less film shrinkage in the curing step, has good coated surface state and excellent moisture resistance and adhesion, has small changes in the refractive index under high temperature conditions, and is capable of forming a low-refractive-index film.
    • 用于光学材料的组合物包括由平均组成式(1)表示的倍半硅氧烷获得的聚合物:(R1SiO1.5)x(R2SiO1.5)y(其中R1是可聚合基团,R2是不可聚合基团, x为2.0〜14.0的数,y为2.0〜14.0的数,条件是x + y = 8.0〜16.0,R 1基和R 2基可以相同或不同),并且包括至少一种笼型倍半硅氧烷化合物。 该组合物适合用作光学元件中的抗反射膜,在固化步骤中具有较小的膜收缩率,具有良好的涂覆表面状态和优异的耐湿性和粘附性,在高温条件下的折射率变化小,并且能够 形成低折射率膜。
