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

个别也可能交联在一起，这意味着不同上各个点相互附着。

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

但SPN内部则多是由瞬态间作用力交联，例如氢键。

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

因此，研究人员开发了一个可稍作调整库，这些可以使交联化学键溶解得慢。

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

在混中， 自由基与其他发生反应， 将交联化学键转化为 vitrimer 中发现非永久性类型。
