通过苯乙烯和甲基丙烯酸甲酯的原位自由基聚合，在四甲基乙二胺四乙酸钠（Na-EDTA）水溶液中去除PCP骨架，在不同形貌的多孔配位聚合物（PCP）晶体中有效地制备了非球形聚合物颗粒。在该复制过程中，分离的乙烯基聚合物颗粒保留了原始PCP颗粒的尺寸和形态，尽管聚合物链没有通过交联而稳定。从PCP基质中分离出来后，乙烯基聚合物的这种形态保留通过聚合物的刚性和孔隙率来确保，这通过DSC和吸附测量来证实。从聚合物颗粒的功能性质的观点来看，颗粒中聚合物链的非常规组装是令人感兴趣的。
Nonspherical polymer particles have been efficiently prepared in different morphological crystals of porous coordination polymers (PCPs) by in situ radical polymerization of styrene and methylmethacrylate, followed by removal of the host PCP frameworks in aqueous tetrasodium ethylenediaminetetraacetate (Na-EDTA) solution. In this replication process, the isolated vinyl polymer particles retained the size and morphologies of the original PCP particles, although the polymer chains were not stabilized by cross-linking. This morphological retention of vinyl polymers after the isolation from the PCP matrixes was ensured by the rigidity and porosity of the polymers, which was confirmed by DSC and adsorption measurements. The unconventional assembly of polymer chains in the particles is of interest from the viewpoints of functional properties of the polymer particles.
