I studied some research articles in which researchers had tried to find out the relation of r value with precipitates. Although there experiments indicated that with the increase of r value, polymeric content increases while formation of precipitates take less time. They conducted different analysis including FTIR, XRD and SEM to find out relation of r value with precipitates formation but they concluded with strange result that r value has no effect on structure and morphology of sample.
Can anyone help me out by explaining that why with the increase of r value, stability of sample decreases i.e. precipitates form in relatively less time while keeping in view its no relation with chemical structure?
It depends on the polymer type ,its structural units. Are they polar or non-polar?
You mentioned 'some polymer" in you text .I could help you if I know which are the polymers in your research?
Preformed ferric polymer and its structural formula is [Fe2(OH)n(SO4)3-n/2]m
