Aqueous solutions of polyacrylates, with a wide molar mass distribution, have been equilibrated with aqueous dispersions of calcium carbonate particles. In mixtures with excess polyacrylates, it is found that only a fraction of the original collection of macromolecules adsorbs on the mineral surfaces....
