In this review, the preparation of porous copolymer resin (PCR) materials via suspension polymerization with variable properties are described by tuning the polymerization reaction, using solvents which act as porogens, to yield microporous, mesoporous, and macroporous materials. The porogenic properties of solvents are related to traditional solubility parameters which yield significant changes in the surface area, porosity, pore volume, and morphology of the polymeric materials. The mutual solubility characteristics of the solvents, monomer units, and the polymeric resins contribute to the formation of porous materials with tunable pore structures and surface areas. The importance of the initiator solubility, surface effects, the temporal variation of solvent composition during polymerization, and temperature effects contribute to the variable physicochemical properties of the PCR materials. An improved understanding of the factors governing the mechanism of formation for PCR materials will contribute to the development and design of versatile materials with tunable properties for a wide range of technical applications.
在本综述中，通过悬浮聚合制备具有可变性质的多孔共聚物树脂（PCR）材料的方法被加以描述，即通过调节聚合反应，使用作为致孔剂的溶剂，以制备微孔、介孔和大孔材料。溶剂的致孔性质与传统溶解度参数相关，这些参数会使聚合物材料的表面积、孔隙率、孔体积和形态发生显著变化。溶剂、单体单元和聚合物树脂的互溶特性有助于形成具有可调孔结构和表面积的多孔材料。引发剂溶解度、表面效应、聚合过程中溶剂组成的时间变化以及温度效应的重要性导致了PCR材料具有可变的物理化学性质。对控制PCR材料形成机制的因素有更深入的了解，将有助于开发和设计具有可调性质的多功能材料，以用于广泛的技术应用。
