In a process for stabilizing chemical compounds having at least one ethylenically unsaturated bond to undesired free radical polymerization, a nitroxyl radical and a chemical compound containing phosphorus in chemically bonded form are added to the unsaturated compound present as pure substance or as a component of a mixture.

Em um processo para estabilizar os compostos químicos que têm ao menos uma ligação ethylenically unsaturated a polimerização indesejada do radical livre, um nitroxyl radical e um phosphorus contendo composto químico em formulário quimicamente ligado são adicionados ao presente unsaturated do composto como a substância pura ou como um componente de uma mistura.
