Represented in the image from Russell Varley and colleagues for their article on page 1410 is the impact on the compressive properties of an epoxy network from simply changing the aromatic substitution of tri‐aryl ether epoxy resins from meta to para position. Meta substituted networks are rigid (stiff) and strong as there is no phenylene axis of rotation available. In contrast, para‐substituted networks are more ductile (flexible) due to the additional energy dissipation mechanism provided by the phenylene axis of rotation. (DOI: 10.1002/pol.20200051)

Russell Varley及其同事在其第1410页上的文章中的图像中所代表的是，简单地将三芳基醚环氧树脂的芳族取代基从间位改为对位，会对环网的压缩性能产生影响。由于没有亚苯基旋转轴，间位取代的网络是刚性的（刚性）且坚固。相反，由于亚苯基旋转轴提供了额外的能量耗散机制，对位取代的网络更具延展性（柔性）。（DOI：10.1002 / pol.20200051）
