橡胶网络的机械性能主要取决于交联密度,而聚合物本身的影响相对较小。弹性体的化学结构影响某些方面的性能(例如,耐化学性和耐热性、摩擦、粘合性、气密性、生物相容性等),而对于所有弹性链聚合物来说,中等变形下力学性能大致都是一样的。即使是断裂和疲劳性能,在没有应力诱导结晶或机械稳定性差的键交联(例如离子聚合物)的情况下,也不特别依赖聚合物。也有一些例外,通常是因为其独特的网络结构。其中一个例子就是互穿聚合物网络,其理想状态是一个由两种化学性质不同的组分形成的共连续的互 The mechanical properties of the rubber network mainly depend on the crosslinking density, while the polymer itself has a relatively small effect. The chemical structure of the elastomer affects certain aspects of performance (eg, chemical and thermal resistance, friction, adhesion, air-tightness, biocompatibility, etc.) while for all elastomeric chain polymers moderate Mechanical properties under deformation are generally the same. Even in the case of fracture and fatigue properties, polymers are not particularly reliant upon stress-induced crystallization or poor crosslinking of the bond, such as ionic polymers. There are some exceptions, usually because of their unique network structure. One such example is the interpenetrating polymer network, which ideally consists of a co-continuous pair of two chemically distinct components
