Patent ID: 8779178

Claim:
A process for making a hydrolysis-resistant silicone compound having a sterically hindered terminal silicon group, the process comprising the step of reacting an alkoxysilyl compound having the structure: with one or more silyl halide compounds having the structure: wherein X 1 , X 2 , and X 3 independently represent a halogen selected from the group consisting of chlorine, bromine, and iodine; wherein M represents a radical-polymerizable group; wherein L represents an optionally substituted divalent C 1 -C 20 organic group; wherein n represents an integer of from 0 to 200; wherein Q 1 , Q 2 , and Q 3 independently represent hydrogen or a hydrolyzable group; wherein Z 1 to Z 11 independently represent optionally substituted C 1 -C 20 alkyl groups or optionally substituted C 6 -C 20 aryl groups, with the provisos that: at least one of Z 3 , Z 4 , and Z 9 is methyl, and at least one is an organic group having at least two carbon atoms, at least one of Z 5 , Z 6 , and Z 10 is methyl, and at least one is an organic group having at least two carbon atoms, and at least one of Z 7 , Z 8 , and Z 11 is methyl, and at least one is an organic group having at least two carbon atoms; wherein a, a′, b, b′, c, and c′ independently represent integers of from 0 to 20; and wherein (a+a′), (b+b′), and (c+c′) are, independently, integers of from 0 to 20, with the proviso that (a+a′), (b+b′), and (c+c′) are not simultaneously 0.
