【摘要】 用衣康酸双烯丙酯作交联剂合成以丙烯酸甲酯为骨架的吸附树脂。按照通常方法,测定了它们的比表面积、堆积密度、骨架密度。找到了合成吸附树脂的合适条件。用反相色谱的方法研究了吸附树脂的极性,测定了它对几种小分子的吸附热。由此提出该树脂是一种中等极性中等比表面积的大孔吸附树脂。同时,为树脂的极性研究提供了一种方法。更多还原

【Abstract】 Adsorption resins were synthesized from methyl methacrylate with diallylita-conate as crosslinking agent. Their specific surface areas and apparent and skeletal densities were determined according to conventional methods.We found the optimal conditions under which the resins were prepared.we also investigated the polarity of these adsorption resins by inverse gas chromatography.The adsorption heats for some probe molecules were determined at the same time. The resin prepared was macroporous adsorption resin which has intermediate polarity and specific surface area更多还原
