The formation and structure of zinc polyacrylate has been studied by Fourier transform infrared spectroscopy (FTIR). Using this technique we have shown that the fully hardened cement is bonded predominantly by zinc carboxylate complexes, rather than by associations of purely ionic character as had previously been supposed. Ionic bonds are formed in the initial stages of the reaction but are gradually converted to complex forms. This bond rearrangement appears partly responsible for physical changes that occur during gelation, setting, and hardening.
采用傅里叶变换红外光谱法（FTIR）对聚丙烯酸锌的形成和结构进行了研究。利用该技术我们发现，完全硬化的水泥主要通过羧酸锌络合物结合，而非如之前所认为的那样通过纯离子性质的缔合作用结合。离子键在反应初期形成，但会逐渐转变为络合形式。这种键的重排似乎部分导致了胶凝、凝结和硬化过程中发生的物理变化。
