Research on Coordination Number of CaCl₂-PEG Coordination Polymer

The coordinatton the of CaCl₂ with PEG was studied by IR and XPS. Formation of \mathrmCa^2+ \cdot 4\left(\mathrmO^- \mathrmCH_2-\mathrmCH_2-\mathrmCl_2^-\right. coordination compound and the coordination number of CaCl₂-PEG coordination polyme was measured with conductivity method. The conductvity method is a fast and valid method to study the coordination number of CaCl₂-PEG coordination polymer, it was confirmed by conductivity measurement for coordination number and by studied on ESR and shake-up effect of XPS spectra of CaCl₂-PAAm.
