High Frequency Spectroscopic Study of the Bound State of Water in PEG–H2O System during Heating from Frozen State
High Frequency Spectroscopic Study the Bound State of Water in PEG–H2O System Frozen State
2010/9/17
The bound state of water in PEG (polyethylene glycol)–H2O systems was studied by using HFS and DSC methods. Samples with the mixing ratios EO:H2O = 1:1 (a) and 1:10 (b), where EO indicates the ethylen...
