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。
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.
