摘　　要：由 2 苯氧基乙醇和甲醛一步缩聚法合成了酚醛型聚合物假冠醚 (POCE)。用FTIR光谱监控的方法研究了该酚醛树脂化反应。结果表明 ,在以 2 苯氧基乙醇为单体的酚醛交联反应中 ,除醇醛比例、反应温度和反应时间外 ,浓硫酸的用量是关键因素。聚合物对Na+ 、K+ 、Ca2 + 、Sr2 + 、Hg2 + 和Cu2 + 吸附性能良好 ,吸附容量分别达 1 5 2 5、0 849、2 0 2 7、0 70 9、0 815和 0 4 0 6mmol/g。A phenolic polymeric pseudo crown ether(POCE) was directly synthersized from phenoxy ethanol and formaldehyde in one step. The phenolic resinification was studied by infrared spectrometry. The results show that besides the proportion of phenoxy ethanol to formaldehyde, reaction temperature and time, the crux is the amount of concentrated sulphuric acid used in phenol fromaldehyde condensation when 2- phenoxy ethanol is used as monomer. The polymer has good adsorption properties for Na +, K +, Ca 2+, Sr 2+, Hg 2+, Cu 2+, the adsorption capacities are 1.525, 0.849, 2.027, 0.709, 0.815 and 0.406 mmol/g, respectively.
