• 中文摘要： 本研究製備具有結晶耐隆6硬鏈節及聚(四亞甲基醚)軟鏈節之段式共聚醚醯胺,同時以各種不同方法探討其熱性質,結晶性質,總體性質以及動態模數。在室溫下,僅有耐隆6鏈節可以結晶,由DSC及X-光繞射數據可看出其結晶度隨己內醯胺含量之增加而增高。在室溫下,其抗張強度,模數及Shore D硬度亦隨己內醯胺含量之增加而提高。Shore D硬度與溫度之關係趨勢與動態模數數據一致。此類耐隆6系段式共聚醚醯胺之各種機械性質與商業化PEBAX段式共聚醚醯胺可相抗衡。
• 英文摘要： A series of block copolyetheramides with hard segment of crystalline nylon-6 and soft segment of poly(tetramethylene ether) were prepared. Their thermal properties, crystalline properties, bulk properties and dynamic moduli were investigated with respect to composition. It was found that only nylon-6 segment was crystalline at room temperature, and the crystallinity of the block copolyetheramides increased with increasing caprolactam content as shown by the DSC and X-ray diffraction data. The tensile strength, modulus and Shore D hardness at room temperature increased as the caprolactam content increased. The trend of Shore D hardness as a function of temperature was consistent with that of dynamic modulus data. In conclusion, the mechanical properties of these nylon-6 based block copolyetheramides were comparable with those of commercial block copolyetheramides (PEBAX)
