用群子统计理论研究了热敏型高分子合金体系的浊度随相态转变的过程,建立了二元高分子合金体系的线性群子统计模型,推导出该体系的相分离方程,并得到一系列热敏型高分子合金相转变群子统计参数,并进一步在理论上解释了不同剪切速率下相态转移群子参数的变化规律:相态转变群子参数r1.r2随着剪切速率的增大而减小,即相容性得到改善。并提出了8种不同类型高分子合金相图,在群子统计理论的基础上成功地模拟了实际曲线,得到了相当吻合的理论模拟曲线。
Using the theory of sub-population statistics, the turbidity change with the phase transition of the thermosensitive macromolecule alloy system was studied. A linear population statistical model of the binary macromolecular alloy system was established. The phase separation equation of the macromolecule alloy system was deduced. A series of statistical data of the transition matrix of the thermosensitive macromolecule alloy phases and further explain the variation regularity of the phase transition subgroup parameters under different shear rates theoretically: Phase transition subgroup parameter r1.r2 With the shear The rate of increase decreases, that is, the compatibility is improved. And eight different types of polymer alloy phase diagrams are proposed. Based on the population statistics theory, the actual curve is successfully simulated and the theoretical simulation curve is obtained.
