| 摘要 |
The present invention generally relates to compounds and methods for inhibiting the radical polymerization of unsaturated compounds, particularly vinyl monomers. More particularly, it relates to the use of stable hydroxyl amines to inhibit the polymerization of unsaturated compounds (e.g., vinyl monomers) wherein said stable hydroxylamine is soluble in organic solvents, particularly hydrocarbon solvents consisting of unsaturated and, therefore, polymerizable constituents. |

1. A hydroxylamine compound having the structure of Formula 1:wherein
R1 is alkyl, aryl, alkaryl, heterocyclo, or —C(O)R6; R2, R3, R4, and R5, are independently selected from the group consisting of alkyl, alkylaryl, aryl, heteroaryl, or R2 and R3 or R4 and R5 together can form a spiro ring; and R6 is alkyl, alkylaryl, aryl, or heteroaryl. |
