  • Method for Immediately Terminating Radical Polymerizations, Inhibitor Solution, and Use Thereof
    Publication number: 20150337056
    Abstract: A method is described for immediately terminating free radical polymerizations by adding an inhibitor solution comprising a phenothiazine compound and/or a monoalkyl ether of hydroquinone to the free radical polymerizing system. The method is characterized in that the solvent of the inhibitor solution comprises at least 50% by weight of said solvent of alkylene glycol and/or polyalkylene glycol and/or terminally etherified derivatives of alkylene glycol and/or of polyalkylene glycol. The method permits the use of nontoxic inhibitor solutions. Inhibitor solutions are also described which comprise a phenothiazine compound and/or a monoalkyl ether of hydroquinone and, as solvent, alkylene glycol and/or polyalkylene glycol and/or terminally etherified derivatives of these compounds.
