摘要 利用DSC和偏光显微镜研究了聚乙二醇在超临界CO2 中的结晶情况 ,超临界条件下得到的晶粒小而均匀 ,DSC测试还表明超临界CO2 可提高聚乙二醇的熔眯和溶解焓。 Crystallization of polyethylene glycol was undertaken in supercritical carbon dioxide.The result of crystallization was observed with DSC and polarizing microscope.Homogeneous microlites were obtained while melting point and melting enthalpy was increased in SC_CO 2.
