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

但SPN内部的聚合物则更多态分子间作用力交联的，例如氢键。

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，这意味着不同聚合物上的各点相互附着。

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

因此，研究人员开发可稍作调整的分子库，这些分子可以使交联化学键溶解得更慢。

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， 自基与其他分子发生反应， 将交联的化学键转化为 vitrimer 中发现的非永久性类型。
