    Abstract: Phosphorus-free inhibitor compositions containing (a) N-oxyl radical(s) and (b) a phenol, optionally substituted with up to three 1-4C alkyl, 2-4C alkenyl or 7-10C aralkyl groups. Phosphorus-free inhibitor compositions (I) containing (a) N-oxyl radical(s) and (b) a compound of formula (X). n = 0-3; R = 1-4C alkyl, 2-4C alkenyl or 7-10C aralkyl. Independent claims are also included for: (i) a method for stabilizing materials containing ethylenic double bond(s) against unwanted polymerisation by adding (I) to the material; (ii) a mixture containing an ethylenically unsaturated compound and an effective amount of (I) as polymerisation inhibitor.
