Individual polymers may also be crosslinked together, which means that various points on different polymers are attached to each other.

别聚合物也可能交联在一起，这意味着不同聚合物上点相互附着。

But polymers within the SPN are crosslinked by more transient intermolecular forces, such as hydrogen bonding.

但SPN内部聚合物则多是由瞬态分子间作用力交联，例如氢。

So, the researchers developed a library of slightly-tweaked possible molecules that might be slower to dissolve a crosslinked bond.

因此，研究人员开发了一可稍作调整分子库，这些分子可以使交联化学溶解得慢。

In the mix, the radicals react with other molecules to convert crosslinked chemical bonds into the non-permanent types found in vitrimers.

在混合物中， 自由基与其他分子发生反应， 将交联化学转化为 vitrimer 中发现非永久性类型。
