Here, one‐step synthesis of high molecular weight poly(methyl methacrylate) (PMMA; 1000–1650 kg mol⁻¹) is reported by using zeolitic imidazole framework‐8 (ZIF‐8) catalyst without any co‐catalyst in the absence of a solvent. This type of high molecular weight PMMA has different applications, mainly in gel polymer electrolyte and bone cement. Zwitterionic type mechanism is proposed where the active acid site of the catalyst dominates for initiation of polymerization. Without any significance loss of structural morphology and catalytic activity, ZIF‐8 can easily be recycled for further uses. ZIF‐8 exhibits superior activities for the synthesis of high molecular weight PMMA compared to the heterogeneous catalysts mentioned earlier.

使用可回收和可再利用的沸石咪唑Framework-8催化剂合成高分子量聚甲基丙烯酸甲酯

此处报道了在不存在任何助催化剂的情况下，使用不带任何助催化剂的沸石咪唑骨架-8（ZIF-8）催化剂一步合成高分子量聚甲基丙烯酸甲酯（PMMA； 1000-1650 kg mol ^-1）的方法。溶剂。这种类型的高分子量PMMA具有不同的应用，主要用于凝胶聚合物电解质和骨水泥中。提出了两性离子型机理，其中催化剂的活性酸位点主导聚合反应。ZIF-8可以很容易地回收再利用，而不会显着降低结构形态和催化活性。与前面提到的非均相催化剂相比，ZIF-8在合成高分子量PMMA方面显示出优异的活性。
