Curable organopolysiloxane composition, optical device sealing material, and optical device |
摘要 |
The present invention is a curable organopolysiloxane composition containing (A) a compound shown by the following average composition formula (1), wherein R1 represents an aliphatic unsaturated group, R2 represents a monovalent hydrocarbon group, R3 represents an aliphatic hydrocarbon group, Ar represents an aryl group, and “n” and “m” represent positive numbers which satisfy n≧1, m≧1, and n+m≧10, (B) a hydrogen atom-containing organic silicon compound having at least two silicon atom-bonded hydrogen atoms per one molecule while not having an aliphatic unsaturated group, and (C) a hydrosilylation catalyst which contains a platinum group metal. Thereby, there can be provided a curable organopolysiloxane composition which can give a cured product having high transparency, high refractive index, and excellent thermal shock resistance; an optical device sealing material; and an optical device.; |

1. A curable organopolysiloxane composition containing:
(A) a compound shown by the following average composition formula (1), wherein R1 represents the same or different aliphatic unsaturated groups; R2 represents the same or different unsubstituted or substituted monovalent hydrocarbon groups; R3 represents the same or different unsubstituted or substituted aliphatic hydrocarbon groups; Ar represents the same or different unsubstituted or substituted aryl groups which may contain a heteroatom; and “n” and “m” represent positive numbers which satisfy n≧1, m≧1, and n+m≧10, (B) a hydrogen atom-containing organic silicon compound having at least two silicon atom-bonded hydrogen atoms per one molecule while not having an aliphatic unsaturated group, and (C) a hydrosilylatation catalyst which contains a platinum group metal, wherein the compound shown by the formula (1) of the component (A) is synthesized via a cyclic oligomer shown by the following average composition formula (2), wherein R3 and Ar represent the same meanings as before; and n′ and m′ represent positive numbers which satisfy n′≧1 and m′≧1, and wherein the curable organopolysiloxane composition further contains the cyclic oligomer shown by the formula (2). |
