| 摘 要： | 实验测定了PEG(M~n=200),PEG(M~n=300),PEG(M~n=400),PDMS(M~w=15000)和PDMS(M~w=20000)在20-90℃温度范围的热压力系数和密度,它们的热压力系数和内压几乎与分子量无关。据此还建立了一个聚合物内压的对应状态模型,它只含一个可调参数,能满意地适用于各种聚合物。

| Abstract: | The thermal pressure coefficients and densities of PEG (M~n=200), PEG (M~n=300), PEG (M~n=400), PDMS (M~w=15000) and PDMS (M~w=20000) have been measured over the temperature range of 20-90℃. It is found that their thermal pressure coefficients and internal pressures are almost in dependent of the molecular weight. A corresponding state model of internal pressure with only one adjustable parameter for polymers is established, which can be applied to various polymers satisfactorily. |
