EPDMのトレッドポリマーとしての特性について主に耐摩耗性に重点をおいて検討した.各種EPDMの実験室的検討および実走試験の結果から, EPDMの耐摩耗性はポリマームーニ粘度のほかにエチレン含量に大きく左右され, ポリマームーニ粘度およびエチレン含量が高いと耐摩耗性は向上するが逆に常温での可塑性が低下し, タイヤの成形時の加工性が悪くなることがわかった. したがって, ポリマーの選定にあたっては両者のつり合いを充分考える必要がある. 今回検討したEPDMの中では1,4-ヘキサジエンを第3成分としたものが最も耐摩耗性, 加工性などのバランスがとれているが, これが第3成分による差か, それとも分子量分布など他の要因に基づくものかはさらに検討する要がある ...
