紫外线固化性硅酮组合物及其固化物、以及含有该组合物的光学元件封装材料
Abstract:
一种紫外线固化性硅酮组合物。所述组合物包含：(A)以下述通式(1)表示的有机聚硅氧烷100质量份、以及(B)光聚合引发剂0.1～10质量份。其中，在通式(1)中，n为满足1≤n≤100的数；Ar为芳香族基团；F1和F2彼此独立地为选自以下述通式(2)、下述通式(3)表示的基团中的基团；相对于以F1和F2所示的全部末端基团的总计个数，以下述通式(3)所表示的末端基团的个数比例为20％以上。在通式(2)中，R1彼此独立地为碳原子数1～20的一价烃基。在通式(3)中，m为满足0≤m≤10的数，R1彼此独立地为碳原子数1～20的一价烃基，R2为氧原子或亚烷基，R3为丙烯酰基、甲基丙烯酰基、丙烯酰氧基烷基或甲基丙烯酰氧基烷基。
Abstract(English):

A UV curable silicone composition comprises: (A) 100 parts by mass of an organopolysiloxane represented by formula (1) wherein n represents a number satisfying 1 <= n <= 100, Ar represents an aromatic group, each of F 1 and F 2 is selected from groups of formulae (2) and (3), and a ratio of the number of terminal groups of the formula (3) to a total number of all the terminal groups is not lower than 20%, wherein each R 1 represents a monovalent hydrocarbon group having 1 to 20 carbon atoms, wherein m represents a number satisfying 0 <= m <= 10, each R1 represents a monovalent hydrocarbon group having 1 to 20 carbon atoms, R2 represents an oxygen atom or an alkylene group, and R3 represents an acryloyl group, a methacryloyl group, an acryloyloxyalkyl group or a methacryloyloxyalkyl group; and (B) 0.1 to 10 parts by mass of a photopolymerization initiator.
