Abstract

A siloxane compound comprises a plurality of siloxane repeating units and at least a portion of the siloxane repeating units are cyclosiloxane repeating units conforming to a specified structure. A process for producing such siloxane compounds is also provided. A process and kit for producing a cross-linked silicone polymer using the described siloxane compounds is also provided. A light emitting diode (LED) comprises an encapsulant, and the encapsulant comprises a cross-linked silicone polymer produced from the described siloxane compounds.

First claim

What is claimed is:

1. A compound conforming to the structure of Formula (LXX)

wherein R 70 and R 71 are independently selected from the group consisting of haloalkyl groups, aralkyl groups, aryl groups, substituted aryl groups, heteroaryl groups, and substituted heteroaryl groups; c is 0 or a positive integer from 1 to 3; R 72 , R 73 , R 74 , R 75 , R 76 , R 77 , R 78 , R 80 , R 81 , R 82 , R 83 , R 84 , R 85 , and R 86 are independently selected from the group consisting of alkyl groups, substituted alkyl groups, cycloalkyl groups, substituted cycloalkyl groups, alkenyl groups, substituted alkenyl groups, cycloalkenyl groups, substituted cycloalkenyl groups, heterocyclyl groups, substituted heterocyclyl groups, aryl groups, substituted aryl groups, heteroaryl groups, substituted heteroaryl groups, trialkylsiloxy groups, aryldialkylsiloxy groups, alkyldiarylsiloxy groups, and triarylsiloxy groups; provided, if c is 0, then R 74 and R 82 are independently selected from the group consisting of haloalkyl groups, aralkyl groups, aryl groups, substituted aryl groups, heteroaryl groups, and substituted heteroaryl groups.

2. The compound of claim 1 , wherein R 70 and R 71 are independently selected from the group consisting of aryl groups.

3. The compound of claim 2 , wherein R 70 and R 71 are each phenyl groups.

4. The compound of claim 1 , wherein R 72 , R 73 , R 74 , R 75 , R 76 , R 77 , R 78 , R 80 , R 81 , R 82 , R 83 , R 84 , R 85 , and R 86 are independently selected from the group consisting of alkyl groups and aryl groups.

5. The compound of claim 4 , wherein R 72 , R 73 , R 75 , R 76 , R 77 , R 78 , R 80 , R 81 , R 83 , R 84 , R 85 , and R 86 are independently selected from the group consisting of alkyl groups; and R 74 and R 82 are independently selected from the group consisting of aryl groups.

6. The compound of claim 5 , wherein R 72 , R 73 , R 75 , R 76 , R 77 , R 78 , R 80 , R 81 , R 83 , R 84 , R 85 , and R 86 are methyl groups; and R 74 and R 82 are phenyl groups.

7. The compound of claim 1 , wherein c is 1.

8. The compound of claim 7 , wherein R 72 , R 73 , R 75 , R 76 , R 77 , R 78 , R 80 , R 81 , R 83 , R 84 , R 85 , and R 86 are methyl groups; and R 74 and R 82 are phenyl groups.

9. The compound of claim 1 , wherein c is 0; R 72 , R 73 , R 75 , R 76 , R 77 , R 78 , R 80 , R 81 , R 83 , R 84 , R 85 , and R 86 are methyl groups; and R 74 and R 82 are phenyl groups.
