Poly(methyl methacrylate) (PMMA) is widely used in aviation, architecture, medical treatment, optical instruments and other fields because of its good transparency, chemical stability and electrical insulation. However, the application of PMMA largely depends on its physical properties. Mechanical properties such as tensile strength, fracture surface energy, shear modulus and Young's modulus are increased with the increase in molecular weight. Consequently, it is of great significance to synthesize high molecular weight PMMA. In this article, we review the application of conventional free radical polymerization, atom transfer radical polymerization (ATRP) and coordination polymerization for preparing high molecular weight PMMA. The mechanisms of these polymerizations are discussed. In addition, applications of PMMA are also summarized.
聚甲基丙烯酸甲酯（PMMA）因其良好的透明度、化学稳定性和电绝缘性而广泛应用于航空、建筑、医疗、光学仪器等领域。然而，PMMA的应用在很大程度上取决于其物理性能。诸如拉伸强度、断裂表面能、剪切模量和杨氏模量等机械性能会随着分子量的增加而提高。因此，合成高分子量的PMMA具有重要意义。在本文中，我们综述了传统自由基聚合、原子转移自由基聚合（ATRP）和配位聚合在制备高分子量PMMA方面的应用。讨论了这些聚合反应的机理。此外，还总结了PMMA的应用。
