Six new networklike thiacrown ether polymers (NTCPs) were synthesized by a new method
which is the copolymerization of ethylene glycol bisglycidyl ether or diethylene glycol bisglycidyl ether with 2-alkoxymethylthiiranes. The structure of these polymers was studied with IR
DTA
elemental analysis and scanning electron microscope. It is shown that these polymers have very high complexing capacities with potassium and sodium ions and have good phase transfer catalysis activity.
