摘要： PROBLEM TO BE SOLVED: To provide a non-conjugate cyclic diene and its composition capable of producing a (co)polymer with high polymerizing activity and a process for production of a non-conjugate cyclic diene polymer capable of producing the (co)polymer with high polymerizing activity. SOLUTION: The non-conjugate cyclic diene satisfies at least one of (1) a specific amount or less of a compound having seven membered triene hydrocarbon structure and (2) a specific amount or less of a conjugated polyene compound having bicyclic eight membered hydrocarbon structure. The process for production of the non-conjugate cyclic diene polymer provides the non-conjugate cyclic diene for (co)polymerization using an olefinic polymerization catalyst containing an organic aluminumoxy compound and/or an ionized ionic compound. The process for production uses the polymerization of a crude non-conjugate cyclic diene after contacting with an alkali followed by removal of at least a part of low boiling fraction and at least a part of high boiling point fraction.
