Patent number: 6960279Abstract: Disclosed is the observation that 7-aryl-quinone methides and 4-tert-butylcatechol, when used in combination in a vinyl aromatic monomer to inhibit polymerization,do not inhibit polymerization to the same extend as each would if used separately. Stated another way, a phenomenon has been observed that when these two compounds are used together, they can, to a large extent, render each other unable to inhibit polymerization in a vinyl aromatic monomer. Also disclosed are methods of preventing adverse results of this interaction when undesired and a method of using this interaction to prepare a reactive vinyl aromatic monomer having a concentration of 4-tert-butylcatechol that would otherwise inhibit polymerization. The invention is disclosed to be useful with the production and storage of any vinyl aromatic monomer and is disclosed to be particularly useful with the production and storage of styrene monomer.Type: GrantFiled: May 6, 2002Date of Patent: November 1, 2005Assignee: Fina Technology, Inc.Inventor: James T.
