A v a i l a b l e in 5 0 - a n d 1 0 0 - p o u n d drums. manufacturers have long searched ^ for a monomer stabilizer which is effective at storage temperatures but which is easily deactivated when polymerization is desired. 2,5-Ditertiary Butyl Hydroquinone offers an answer to this problem. In the presence of peroxides or oxygen at polymerization temperatures, it is converted

to 2,5-Ditertiary Butyl Quinone. For vegetable oils, the latter product is a polymerization catalyst. For styrene and other vinyls, the Quinone has no appreciable depressing effect on the polymerization rate. For economical removal of stabilizer before polymerization, try 2,5-Ditertiary Butyl Hydroquinone.
