無機充填材としては、ゴム工業界において、通常使用される無機化合物である限り、特に制限はない。使用できる無機化合物としては、例えば、シリカ;γ−アルミナ、α−アルミナ等のアルミナ(Al2O3);ベーマイト、ダイアスポア等のアルミナ一水和物(Al2O3・H2O);ギブサイト、バイヤライト等の水酸化アルミニウム[Al(OH)3];炭酸アルミニウム[Al2(CO3)3]、水酸化マグネシウム[Mg(OH)2]、酸化マグネシウム(MgO)、炭酸マグネシウム(MgCO3)、タルク(3MgO・4SiO2・H2O)、アタパルジャイト(5MgO・8SiO2・9H2O)、チタン白(TiO2)、チタン黒(TiO2n−1)、酸化カルシウム(CaO)、水酸化カルシウム[Ca(OH)2]、酸化アルミニウムマグネシウム(MgO・Al2O3)、クレー(Al2O3・2SiO2)、カオリン(Al2O3・2SiO2・2H2O)、パイロフィライト(Al2O3・4SiO2・H2O)、ベントナイト(Al2O3・4SiO2・2H2O)、ケイ酸アルミニウム(Al2SiO5、Al4・3SiO4・5H2O等)、ケイ酸マグネシウム(Mg2SiO4、MgSiO3等)、ケイ酸カルシウム(Ca2・SiO4等)、ケイ酸アルミニウムカルシウム(Al2O3・CaO・2SiO2等)、ケイ酸マグネシウムカルシウム(CaMgSiO4)、炭酸カルシウム(CaCO3)、酸化亜鉛(ZnO)、硫酸バリウム(BaSO4)、酸化ジルコニウム(ZrO2)、水酸化ジルコニウム[ZrO(OH)2・nH2O]、炭酸ジルコニウム[Zr(CO3)2]、各種ゼオライトのように電荷を補正する水素、アルカリ金属又はアルカリ土類金属を含む結晶性アルミノケイ酸塩等が挙げられる。これらの無機充填材は、ゴム成分との親和性を向上させるために、該無機充填材の表面が有機処理されていてもよい。
カーボンブラックとしては、特に制限はなく、例えば、市販品のカーボンブラック、Carbon-Silica Dual phase filler等が挙げられる。ゴム成分にカーボンブラックを含有することにより、ゴムの電気抵抗を下げて、帯電を抑止する効果、さらにゴムの強度を向上させる効果を享受できる。
本発明のゴム組成物には、上記テトラジン化合物(1)、並びに無機充填材及び/又はカーボンブラック以外にも、ゴム工業界で通常使用される配合剤、例えば、硫黄等の加硫剤を配合することができる。本発明のゴム組成物には、さらに、別の配合剤、例えば、老化防止剤、オゾン防止剤、軟化剤、加工助剤、ワックス、樹脂、発泡剤、オイル、ステアリン酸、亜鉛華(ZnO)、加硫促進剤、加硫遅延剤等を配合してもよい。これら配合剤は、本発明の目的を害しない範囲内で適宜選択して配合することができる。これら配合剤としては、市販品を好適に使用することができる。
本発明のゴム組成物の製造方法としては、特に制限されず、従来より公知の方法により製造することができ、例えば、ジエン系ゴム、テトラジン化合物(1)、並びに、必要に応じて無機充填材及び/又はカーボンブラックを含む原料成分を混練する工程(A)、並びに工程(A)で得られる混合物、及び加硫剤を混練する工程(B)を含む方法が挙げられる。

工程(B)は、工程(A)で得られる混合物、及び加硫剤を混合する工程であり、混練の最終段階を意味している。
このようにして得られたゴム組成物は、防振ゴム用、免震ゴム用等の各種ゴム部材に用いることができる。
