The present invention addresses the problem of providing a copolymer containing at least an acyclic non-conjugated olefin unit and a conjugated diene unit, and having a high elastic modulus. This copolymer contains at least an acyclic non-conjugated olefin unit and a conjugated diene unit, and is characterized in that the difference (Tem-Tim) between an extrapolated melting end temperature (Tem) as measured in accordance with JIS K7121 and an extrapolated melting initiation temperature (Tim) as measured in accordance with JIS K7121 is not higher than 60 DEG C.

    本发明解决了提供一种至少含有非环状非共轭烯烃单元和共轭二烯单元并且具有高弹性模量的共聚物的问题。该共聚物至少含有非环状非共轭烯烃单元和共轭二烯单元,并且其特征在于,根据JIS K7121测量的外推熔化结束温度(T)与根据JIS K7121测量的外推熔化起始温度(T)之差(T‑T)不高于60℃。
