各重合体に対して変性の前と後に、Monsanto社製のMV2000EでLarge Rotorを用いて100℃でRotor Speed 2±0.02rpmの条件でムーニー粘度(ML1+4、@100℃)を測定した。この際に用いられた試料は、室温(23±3℃)で30分以上放置した後、27±3gを採取してダイキャビティの内部に満たしておき、プラテン(Platen)を作動させてトルクを印加しながらムーニー粘度を測定した。また、ムーニー粘度の測定後、トルクが緩みながら現れるムーニー粘度の変化を1分間観察し、その勾配値から-S/R値(絶対値)を決定した。

各ゴム試片に対し、ASTM D5963に準じてDIN摩耗試験を進め、損失重量(mg)と比較例2の測定値を基準にしてDIN loss index(損失体積指数(loss volume index):ARIA(Abration resistance index,Method A)で示した。数値が高いほど優れることを示す。
Index=(測定値/基準値)×100
[数式3]
Index=(基準値/測定値)×100
