Abstract
A curable composition comprises: at least one aliphatic carbosilane having m Si—H groups, at least one aliphatic carbosilane having n vinyl groups, and at least one hydrosilylation reaction catalyst. m is an integer greater than or equal to 2, n is an integer greater than or equal to 2, and m+n is at least 5. A cured reaction product and an electronic article including the same are also disclosed.
Claims15
A curable composition comprising components:
- a) at least one aliphatic carbosilane having m Si—H groups, wherein m is an integer greater than or equal to 3, wherein the at least one aliphatic carbosilane having m Si—H groups is represented by the formula:
- HSi(R1)2R2Si(R1)2H
- wherein:
- each R1 independently represents an alkyl group having from 1 to 4 carbon atoms;
- and
- each R2 independently represents an alkylene group or a divalent carbosilane group having up to 50 carbon atoms;
- b) at least one aliphatic carbosilane having n vinyl groups, wherein n is an integer greater than or equal to 2, wherein m+n is at least 5;
- and
- c) at least one hydrosilylation reaction catalyst.
