The speciation of some high molecular weight polycarboxylates was studied in different ionic media. Polyacrylates here investigated (W=2.0, 5.1 and 20.0 kDa) form weak species with alkali metal cations (K=10 2 mol l À1 , t=25 jC, I=0 mol l À1 ) and quite stable complexes with alkaline earth metal ca
