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 ...

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.Influence of acrylonitrile (ACN) content on the processing behavior and morphological development of PA/NBR thermoplastic vulcanizates. Torque‐time profiles, SEM, and SEM/AFM images show that an intermediate ACN level (38%) promotes improved phase dispersion and morphological uniformity, especially with increased processing time, resulting in the most ...

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres
Advanced Functional Materials, Volume 36, Issue 19, 5 March 2026.MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...

Journal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.Dynamic vulcanization at higher shear rates refines PA/NBR morphology, reduces domain size, and maintains mechanical performance after reprocessing. ABSTRACT Thermoplastic vulcanizates (TPVs) of polyamide 6 and nitrile butadiene rubber (PA/NBR) present excellent mechanical properties but traditionally suffer from performance loss during re‐melt ...
