A composition of an ethylenically unsaturated organic compound capable of addition polymerization stabilized from premature polymerization in the liquid phase by the addition of stabilizing amounts of a combination of a cerium compound soluble in said ethylenically unsaturated organic compound and a phenolic type inhibitor, said ethylenically unsaturated organic compound being selected from the group consisting of acrylic acid, methacrylic acid, vinyl acetate, styrene, acrylonitrile, vinyl chloride, acrylamide, n-methylolacrylamide, glycidyl methacrylate, alkyl acrylate and methacrylate esters wherein the alkyl groups contain from 1 to 10 carbon atoms, and esters of acrylic acid and a saturated aliphatic polyol having 2 to 10 carbon atoms and 2 to 5 hydroxy groups, said esters each containing 2 to 5 acrylate groups.
