摘要
A series of calix\ 1,4 crown based polymers with stable conformations were synthesized by reacting calix\ 1,4 crown tetraester with poly(ethyleneimine), and their adsorption capabilities were studied . Their structures and shapes were characterized by elemental analyses, IR and SEM techniques. Their adsorption selectivities were found to be higher than that of calix\arene polymer without stable conformation. All of them showed good selective adsorption capability towards Cu 2+ among the tested cations. The adsorption capacity of compound 2a towards Cu 2+ at concentration of 0 2 mmol/L were 64 5×10 -5 mol/mg.
