Miscibility of C60-end-capped poly(ethylene oxide) with poly(p-vinylphenol)

Abstract

A fullerene (C60)-end-capped poly(ethylene oxide) (FPEO) has been prepared by the cycloaddition reaction of monoazido-terminated poly(ethylene oxide) with C60. The majority of the FPEO sample is the mono-adduct as shown by thermogravimetry and X-ray photoelectron spectroscopy. Most electronic characteristics of C60 are retained in the polymer as shown by its UV-visible absorption spectrum. The incorporation of C60 reduces the extent of crystallinity of PEO by 17%. The miscibility behavior of FPEO with poly(p-vinylphenol) (PVPh) was studied. Similar to PEO, FPEO is miscible with PVPh over the entire composition range. The hydrogen-bonding interaction between FPEO and PVPh is as strong as that between PEO and PVPh as shown by Fourier-transform infrared spectroscopy. © Wiley-VCH Verlag GmbH, 2000.
