| 제목 | The Effect of Temperature on the Infrared Spectra of Segmented Block Copolyesters |
| 초록 | The temperature effect of segmented block copolyetheresters based on poly(butylene terephthalate) and poly(tetramethylene ether glycol) with various hard segment contents were investigated by IR temperature study. The number average molecular weights of poly(tetramethylene ether glycol) (PTMG) used were 2000 and the content of poly(butylene terephthalate) were 35, 65, 100%. Spectral changes were observed on heating the solvent-casting films of copolyetheresters from 30℃ to 250℃. These spectral changes including intensity variation and frequency shifts were found to be dependent on the measurement temperature due to the changes in intramolecular and intermolecular forces as the temperature changes. |
