Synthesis and characterization of alpha,omega-heterofunctional poly(ethylene oxide) macromonomers

摘要

A novel alpha,omega-heterofunctional poly(ethylene oxide) (PEO) macromonomer possessing methacryloyl and thienyl end groups was prepared by ring-opening polymerization of ethylene oxide initiated by potassium thienylethoxide and termination of the living PEO ends with methacryloyl chloride. Incorporation of methacryloyl and thienyl groups was confirmed by free-radical and oxidative polymerization processes, respectively, and by means of H-1 NMR analysis. [References: 20]
