Studies on Synthesis and FTIR Spectra of Novel Polymeric Azacrown Pseudo Ether

Using phenol as initial material, a novel crosslinking phenolic type polymer containing azacrown ether of functional group was synthesized by first polymerization, then functionalization and Na template-guided method. Using FTIR spectra for tracking monitor, better conditions of synthetic reactions and FTIR data of a series of polymers were achieved. The structures of the polymer and its middle products were proved from FTIR and elemental analysis data and other subsidiary methods. FTIR spectra of complexes of the polymer with metallic ions were studied. The results showed that not only -CH_2OCH_2-,-CH_2NCH_2- and phOCH_2 could chelate metal ions, but also CH_2OH did so to a certain extent in the above complexes of Na and Ca 2 .
