本研究阐明了一种机械化学聚合反应对超交联聚合物作为一种替代传统的溶剂为基础的程序。快速和无溶剂的Friedel-Crafts烷基化反应产生的多孔聚合物的表面积高达1720 m（2）g（-1）和孔体积高达1.55 cm（3）g（-1）。LAG（液体辅助研磨）的应用揭示了液体的沸点对所获得的聚合物材料的织构性质的深刻影响。最后，通过苯和环己烷的蒸汽吸附实验对材料进行了表征。
This study elucidates a mechanochemical polymerization reaction towards a hyper-crosslinked polymer as an alternative to conventional solvent-based procedures. The swift and solvent-free Friedel-Crafts alkylation reaction yields a porous polymer with surface areas of up to 1720 m(2)g(-1) and pore volumes of up to 1.55 cm(3)g(-1). The application of LAG (liquid-assisted grinding) revealed a profound impact of the liquid's boiling point on the textural properties of the obtained polymer materials. Finally, the materials are characterized by vapour sorption experiments with benzene and cyclohexane.
