摘　　要：利用 p VT10 0分析仪测得交联聚乙二醇的 p- V- T数据 ,并应用 Sanchez- Lacombe格子流体理论拟合出其 p VT状态方程。同时计算出了交联聚乙二醇 (PEG)的热膨胀系数 α,等温压缩系数 β和热压系数γ,为其在生物化学方面的生产。The pVT data of chemically crosslinked poly(ethylene glycol) were obtained by the pVT100 analyzer. The equation of state in melt state was given by fitting the pVT data by the Sanchez Lacombe Lattice Fluid Theory. The thermal properties of the chemically crosslinked PEG, such as α, β and γ , which may be useful for the application of crosslinked PEG as biochemical materials, were calculated from the pVT data.
