Five new poly-co-condensale of pheaolic and crown ethers were prepared by the condensation of 2
6-dihydroxymethyl-4-phenylphenol with dibenzo-18-crown-6(B18C6)
dibenzo-24-crown-8(2B24C8)
dibenzo-30-crown-10(2B30C10)
benzo-15-crown-5(B15C5)
benzo-18-crown-6(B18C6) respectively and cationbinding abilities were evaluated by extraction of poly-co-con-densates solution in chloroform from aqueous alkali metal picrates solution. The results indicate that the extractability and cation-selectivity of polyco-condensates (PB15C5) and (PB18C6) are more effective than the corresponding monobenzo or dibenzo-crown ethers.
