摘要：The thermal pressure coefficients and densities of PEG((M) over bar(n) = 200), PEG((M) over bar(n) = 300), PEG((M) over bar(n) = 400), PDMS((M) over bar(w) = 15000) and PDMS((M) over bar(w) = 20000) have been measured over the temperature range of 20 similar to 90 degrees C. 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.
