| 摘 要： | 用低分子量模型化合物乙苯与乙酸酐或丙酸酐预混合模拟苯乙烯-顺丁烯二酸酐共聚物(PSMA),乙苯与丙腈预混合模拟苯乙烯-丙烯腈共聚物。用傅里叶变换红外光谱观察这些模型化合物混合前后的谱图变化,发现羟基C=O谱带发生位移。用直接量热法测定的模型化合物的混合热计算相互作用参数B,结果表明MA与AN之间存在较弱的放热相互作用。

| Abstract: | The low molecular weight analogs of styrene/maleic anhydride(PSMA)and styrene/acry-lonitrile (PSAN) copolymer were mixed. The changes in the absorption spectra after mixing were observed by Fourier Transform Infrared Spectroscopy. The small C=O band shifts were found. The measured binary heats of mixing for the liquid analogs were used to calculated the interaction parameters B. The results show that there is specific interaction between the MA and AN units. |
