Abstract
The structure of a Cu2+ complex formed with methacryloyloxyethyl phosphate (PMOE) in polymethylmethacrylate was investigated by optical absorption spe ctra,electron spin resonance and small angle x-ray scattering. Six oxygen a toms from PMOE and H2O ligated to Cu2+ and gave a complex with octahedral s ymmetry. When the molar ratio [P(phosphorous in PMOE)] / [Cu2+] = 2, bident ate chelating PMOE and H2O ligated to Cu2+ in mononuclear complexes. With i ncrease of [P] / [Cu2+], monodentate PMOE replaced bidentate chelating PMOE . In all specimens in the range of 2 less than or equal to [P] / [Cu2+] les s than or equal to 10, mononuclear and polynuclear Cu2+ complexes coexisted and ionic clusters were formed.
