摘要
根据反相气相色谱的热力学理论,讨论了其测定相互作用参数时所存在的问题。以PC/PET共混体系为例,研究温度对高聚物相容性的影响,并预示临界互容温度。
A blend of polycarbonate and poly(ethylene Terephyhalate) was studied by inverse gas chromatography. In agreement with prior studies on polymer blends, the apparent polymer-polymer interaction parameter was found to bc dependent on the chemical nature of the probe. Inverse gas chromatography provides valuable information of the dependence of X with temperature. The critical solution temperature. The critical solution temperature can bc predicated by IGC.
