Abstract: Five new polycondensates of phenolic and crown ethers are prepared by the condensation of 2,6-dihydroxymethyl-4-methoxylphenol with dibenzo-18-crown-6(2B18C6), dibenzo-24-crown-8(2B24C8), dibenzo-30-crown-10 (2B30C10), benzo-15-crown-5 (B15C5), benzo-18-crown-6(B18C6), respectively. The collecting efficiency of polymeric crown ether (PB15C5) for K+, Ag+, Mg2+, Pb2+, Cu2+(10-6-10-4mmol/mL) come close to 100%.

Key words: Condensation, Polymeric crown ether, Complexing extraction, Collecting efficiency
