Abstract: Process for stabilizing polymerizable compounds to polymerization during working-up, storage and/or transport, in which at least one free radical scavenger which contains at least two glycine units is used, with the proviso that the free radical scavenger is not selected from ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA), trans-1,2-cyclohexanediaminetetraacetic acid (CYDTA) and the alkali metal and alkaline earth metal salts thereof.

Abstract: The use of amidoximes for stabilisation of ethylenically-unsaturated compounds against undesired radical polymerisation is disclosed. Combinations of amidoximes with phenol and/or phenothiazine compounds have a synergistic effect. Preferred amidoximes are nitrilotris(acetamidoxime) and nitrilotris(propionamidoxime).
