Title:
STABILIZED 4-OXO-2,2,6,6-TETRAMETHYLPIPERIDINE-1-OXYL-CONTAINING COMPOSITION, POLYMERIZATION INHIBITOR COMPOSITION FOR VINYL COMPOUND, AND METHOD FOR INHIBITING POLYMERIZATION OF VINYL COMPOUND USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/084443
Kind Code:
A1
Abstract:
[Problem] To provide a stabilized 4-oxo-2,2,6,6-tetramethylpiperidine-1-oxyl-containing composition; a polymerization inhibitor composition for a vinyl compound, the polymerization inhibiting ability of which is not greatly impaired even after being kept or stored for a long period of time and which comprises stabilized 4-oxo-2,2,6,6-tetramethylpiperidine-1-oxyl; and a method for inhibiting polymerization of a vinyl compound using the composition. [Solution] A composition in which 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl is blended into 4-oxo-2,2,6,6-tetramethylpiperidine-1-oxyl as a stabilizer thereof; a polymerization inhibitor composition for a vinyl compound which comprises the same; and a method for inhibiting polymerization of a vinyl compound using the composition.
