Two series of crosslinked phenolic resins containing methoxy and polyglycol groups were prepared by cyclopolymn. of 4,4'-dimethoxy polyglycol di-Ph ethers with HCHO or 2,6-bis(hydroxymethyl)-p-methoxyphenol in the presence of H2SO4. These polymers contained pseudo crown ether structures and were characterized by IR, UV, 1H-NMR, and elemental anal. These polymers had good thermal stability and metal chelating capacity, 0.9-3.0 mmol/g, and were useful in the enrichment of metals.
