Zusammenfassung:	PROBLEM TO BE SOLVED: To efficiently separate divinylbenzenes from a mixture comprising m- and p-divinylbenzenes while suppressing reduction in recovery ratio by polymerization, by using a faujasite type zeolite as an adsorbent. SOLUTION: Divinylbenzenes are separated from a mixture comprising m- divinylbenzene and p-divinylbenzene by using a faujasite type zeolite such as a Y type faujasite zeolite substituted with one or more metal ions selected from among rubidium, copper and tin as an adsorbent.
