| 摘 要： | 本文利用ＦＴＩＲ光谱法研究了常温下和升温、降温过程中ＰＨＢ，Ｐ（ＨＯ－ｃｏ－ＨＤ）及不同组分的Ｐ（ＨＢ－ｃｏ－ＨＶ）和Ｐ（ＨＢ－ｃｏ－ＨＨ）共聚物的变化。结果表明，ＰＨＢ、Ｐ（ＨＢ－ｃｏ－ＨＶ）和Ｐ（ＨＢ－ｃｏ－ＨＨ）在变温过程中红外光谱图发生了明显变化，此过程是物理变化，且过程可逆。

| Abstract: | In this paper,PHB,P(HO-co-HD),a various comp os ition of P(HB-co-HV) copolymer and P(HB-co-HH) copolymer were studied both a t normal temperature and in the process of increasing and decreasing temperature using FTIR spectroscopy technology.Results showed that FTIR spectra of PHAs wit h various compositions have distinguishing characteristics.Physical transformati on occurred when PHAs were treated with heat denaturalization,and this physical process was reversible. |
