Additives to prevent degradation of cyclic alkene derivatives
First Claim
1. A stabilized cyclic alkene composition comprising:
- one or more cyclic alkenes, and at least one antioxidant compound of formula (I), wherein R1 through R5 can each independently be H, OH, C1-C8 linear, branched, or cyclic alkyl, C1-C8 linear, branched, or cyclic alkoxy or substituted or unsubstituted aryl; and
wherein said antioxidant compound is present in an amount between about 1 ppm and 200 ppm; and
wherein said composition is purged with at least one gas selected from the group consisting of;
helium, neon, argon, krypton, xenon, radon, nitrogen, carbon monoxide and carbon dioxide, after said composition is introduced to a container intended for storage or shipping of said composition.

Abstract
A stabilized cyclic alkene composition comprising one or more cyclic alkenes, and at least one antioxidant compound having the formula (I),
wherein R1 through R5 can each independently be H, OH, C1-C8 linear, branched, or cyclic alkyl, C1-C8 linear, branched, or cyclic alkoxy or substituted or unsubstituted aryl, and wherein the antioxidant compound is present in an amount between 1 ppm and 200 ppm, and wherein said composition is purged with at least one inert gas after said composition is introduced to a container intended for storage or shipping of said composition. A method for forming a layer of carbon-doped silicon oxide on a substrate, which uses the stabilized alkene composition and a silicon containing compound.
