The extraction ability of the oligomer with selected alkali and transition metals is compared with its monomeric analogous. It has been observed that the oligomer 6 is not selective as compared to its analogae 2 and 3, but shows a remarkable high affinity towards toxic metal cations such as Cu2+, Hg2+ and Pb2+.en10.1081/MA-120006519info:eu-repo/semantics/openAccesscalixarenecopolymerSchiff basephase transferalkalitransition metalArticle3916373Q2WOS:000174710100006Q3
