由于超高分子量聚丙烯酰胺分子链较长,只要在大分子链上有几个交联点,就会形成形成水凝胶造成溶解性急剧下降,本文介绍了交联反应发生的原因以及如何避免该反应的发生。
Due to the long molecular chain of ultra-high molecular weight polyacrylamide, as long as there are several crosslinking points in the macromolecular chain, the formation of hydrogel will cause a sharp drop in solubility. This article describes the reasons for the crosslinking reaction and how to avoid The reaction occurred.
