非线性群子统计理论考察高分子合金的相分离现象

Study on the phase separation of polymer alloys with the non linear sub cluster statistical theory

从统计热力学的角度出发,应用非线性群子统计理论,对高分子合金体系平衡态相分离行为进行了理论研究,建立了二元高分子合金体系的非线性群子统计模型,推导出该体系的相分离方程。在理论和实践的基础上对二元高分子合金体系的相图进行了系统分类,并模拟了若干文献中的相图,得到了与实际曲线相当吻合的理论模拟曲线。

In this paper, the phase separation in equilibrium state has been discussed with the non linear sub cluster statistical theory. The model of non linear sub cluster statistical theory of binary polymer alloys has been established, and the phase separation equation of binary polymer alloys used in the condition of equilibrium has been obtained. On the theoretical and practical bases the phase diagrams of binary polymer alloys have been classified. Many experimental phase diagrams of binary polymer have been simulated by the equation and the simulated curves tallied with the experimental curves.
