通过测定醋酸纤维素（ＣＤＡ）和聚乙烯基吡咯烷酮（ＰＶＰ）共混物溶液的绝对粘度和特性粘数，发现ＣＤＡ和ＰＶＰ分子链段间有缔合现象．用富里哀变换红外光谱（ＦＴＩＲ）研究了共混物的吸收光谱，发现共混物中ＣＤＡ的羟基吸收峰和ＰＶＰ的羰基吸收峰均向低频方向迁移，证明了ＣＤＡ的羟基和ＰＶＰ的羰基之间有氢键形成．研究结果表明ＣＤＡ和ＰＶＰ的相容性及其特殊相互作用来源于不同分子链段间的氢键相互作用．
By measuring the absolute viscosity and intrinsic viscosity of the solution of cellulose acetate (CDA) and polyvinylpyrrolidone (PVP) blend, it was found that CDA and PVP molecular segments have an association phenomenon. The absorption spectra of the blends were studied by Fourier transform infrared spectroscopy (FTIR). It was found that both the hydroxyl absorption peak of CDA and the carbonyl absorption peak of PVP in the blend migrated toward the lower frequency. The hydroxyl groups of CDA and the carbonyl groups of PVP Between the hydrogen bond formation. The results show that the compatibility of CDA and PVP and their special interactions originate from the hydrogen bonding interactions between different molecular chains.
