Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for inhibiting polymerization of olefins which inhibits polymerization of olefins in the production and purification processes of olefins for a long period of time and prevents development of staining due to the adhesion of polymerized products in these processes, thereby improving operational efficiency of these processes and allowing long-term continuous stable operation to be smooth and easy. SOLUTION: The method for inhibiting polymerization of olefins comprises using a piperidine-1-oxyl compound (A) and a p-phenylenediamine compound (B) at the same time in the production and purification processes of olefins, preferably in a weight ratio of (A) to (B) of 99:1 to 1:99.
