Oxidative degradation of crosslinked EPDM elastomers: Impact on the entanglement network
Journal of Polymer Science, Volume 64, Issue 12, Page 2540-2551, 15 June 2026.Entanglement versus chemical crosslink contributions during oxidation‐induced chain scission ageing. ABSTRACT The mechanical behavior of elastomers is mainly governed by the architecture of their macromolecular network. The increase in modulus observed during the oxidation of elastomers that predominantly undergo cross‐linking rather than chain ...

NIPPON GOMU KYOKAISHI, 1970 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 ...

Chemoselective Sequential Polymerization: An Approach Toward Mixed Plastic Waste Recycling
Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.Inspired by biological protein metabolism, this study demonstrates the closed‐loop recycling of mixed synthetic polymers via ring‐closing depolymerization followed by a chemoselective sequential polymerizations process. The approach recovers pure polymers from mixed feedstocks, even in multilayer formats, highlighting a promising strategy to overcome a
