| 摘 要： | 基于聚合物分子间物理相互作用和统计平均场理论,引入附加共聚焓定义,使聚合物分子间的作用得到量化,同时推导出二元共混体系相互作用参数和三元共混体系混合焓关系式.利用所导出的公式解释一些常见聚合物共混体系和增溶体系.导出的关系式很好地解释了聚合物的热力学混溶性,但不能解释聚合物共混增溶作用.

| Abstract: | The excess copolymerization enthalpy was defined to describe the intramolecular intaction within random copolymers, based on statistic physical interaction and the mean field thry. The interaction parameterχblendof the two-component polymer blends and the mixing thalpy of the three-component polymer blends were derived The miscibility of commonly ubinary polymer blends and the compatibility of the three component polymer blends were dcussed in brief. The interaction parameterχblendcould well explain the miscible behavior, not compatible behavior in polymer blends. |
