オルガノポリシロキサンに対する1H−NMR分析は、次の条件で行った。
〈1H−NMR分析内容〉
測定器機:Varian Unity Inova 500MHz NMR
使用溶媒:acetone−d6
測定条件:
Pulse sequence:s2pul
Sweep width:8012.8hz
Acquisition time:2.045 sec
Delay time:2 sec
Pulse width:45 degree pulse(8.10 usec)
Number of scan:16
トルエン500mL、イソプロピルアルコール(IPA)495mL及び水(distilled water)5mLを配合し、測定用溶媒を製造した。また、ベース溶媒(base solution)として0.1Nの濃度のKOH溶液(溶媒:イソプロピルアルコール(IPA))を準備し、標識子(indicator)としては、アルファ−ナフトルベンゼイン(alpha−naphtholbenzein)(pH:0.8〜8.2 yellow、10.0 blue green)を準備した。次いで、試料約1〜2gを採取し、測定用溶媒6gに溶かした後、標識子を添加した後、ベース溶媒で滴定した。滴定完了時点で使用されたベース溶媒の量で酸価(acid value)をmgKOH/gの単位で求めた。
ポリフタルアミド(PPA)で製造された3017 LEDパッケージを使用して素子特性を評価する。具体的に、ポリフタルアミドカップ内に硬化性組成物をディスフェンシングし、70℃で1時間維持した後、さらに150℃で1時間維持して硬化させて、表面実装型LEDを製造する。
