Title:
Aryl group-containing siloxane composition containing alkaline earth metals
Document Type and Number:
Japanese Patent JP6327679
Kind Code:
B2
Abstract:
An aryl group-containing siloxane composition is formed by introducing an alkaline earth-metal as a part of the reaction product of an organopolysiloxane having at least two alkenyl groups per molecule and an organopolysiloxane having at least two silicon-bonded hydrogen atoms per molecule in the presence of a hydrosilylation catalyst, wherein at least one of the organopolysiloxanes includes an aryl group. The alkaline earth metal may be introduced via a heat stability composition or may alternatively be pre-reacted with the organopolysiloxane having at least two alkenyl groups per molecule. The aryl group-containing siloxane compositions may be utilized as an encapsulating layer for a light emitting device.
