Synthesis and properties of Poly (oxyethylene-b-butylene -succinate) ionomers |
| 초록 |
A series of Poly(oxyethylene-b-butylene succinate)ionomers (POBSis) were synthesized by two-step polycondensation of succinic acid and mixed monomers of sodium sulfonateside chain poly(ethylene oxide)(SPEO) and 1,4-butanediol. SPEO was synthesized by grafting the sodium sulfonate on to the chain of poly(ethylene oxide)with molecular weights of 400. The compositon and structure of these segmented ionomers were determined by 1H-NMR spectroscopy. The thermal properties were investigated using DSC. The degree of crystallinity was determined by means of DSC and wide-angle X-ray scattering. A depression of melting temperature and variation of crystallinity of the hard segments with increasing content of SPEO segments were observed. |
