Sep 02, 2003 · The patent disclosure clearly stresses that the cationic polymer is of a relatively high molecular weight of between 500 to 3,000,000 but most, if not all, appear to be at least 10,000 molecular weight and more often, about 500,000 molecular weight. Thus, the cationic ingredient is a large molecule with a low charge density.
