Abstract:
Eine Zusammensetzung zur Sofortbeendigung einer radikalischen Polymerisation enthält: a) einen unter Phenothiazinen ausgewählten Inhibitor der radikalischen Polymerisation, b) ein aprotisches Lösungsmittel, und c) eine ionische Flüssigkeit. Sie dient zur Stabilisierung von radikalisch polymerisierbaren Monomeren gegen radikalische Polymerisation. Zur Sofortbeendigung von radikalischen Polymerisationen setzt man die Zusammensetzung einem radikalisch polymerisierenden System zu.

Abstract:
The invention relates to a composition for immediately ending radical polymerization containing: a) an inhibitor of the radical polymerization selected from among phenothiazines, b) an aprotic solvent, and c) an ionic liquid. Said composition serves to stabilize radically polymerizable monomers against radical polymerization. In order to immediately end radical polymerizations, the composition is added to a radically polymerizing system.
