Abstract
Preparation of some new macrocyclic polyetherdiamides and their complexes with calcium and tetra(4-chlorophenyl) borate is described. The selectivities of these compounds for calcium with respect to ions of the other alkaline earth and alkali metals in poly(vinyl chloride) membranes plasticized with 2-nitro-1-octyloxybenzene are compared.
