PE-gr-PAA

This approach is comparatively widely used, for example to evaluate the formation constants of Cu(II) and Ni(II) complexes with polyethylene-grafted-poly(acrylic acid) (PE-gr-PAA) (Table 3-2), Mn(II)-poly(acrylic acid), for studying sorption of low molecular weight compounds by polymers and complexation with modified silica, etc. [35-37]. It was found that one third of the carboxylic groups failed to react with copper ions in the PE-gr-PAA-Cu(II)-system K = 300 L mor, /n,ax = 0.35). For Cu(II) complexes with polystyrene-grafted-poly(vinylpyridine) of different types the values of K andy],. vary from -2500 to 9100 L moL and -0.15 to 0.37, respectively [38].
