Document Type and Number:
WIPO Patent Application WO/2007/111237
Kind Code:
A1
Abstract:
A method of inhibiting an aromatic vinyl compound from polymerizing during production, purification, storage, or transportation. The method not only inhibits initial polymerization but efficiently inhibits polymerization over long. It imparts excellent handleability to the aromatic vinyl compound.
