Polyamino acids of the formulae (I) and (II):poly(X)npoly(Y)m(I)poly(X')apoly(Y')b(II)wherein each X independently is a polar amino acid, each Y independently is a non-polar amino acid, each X' independently is a polar amino acid, and each Y' independently is a phosphorylated amino acid, and salts of these polyamino acids, are effective as dispersing agents for minerals in aqueous media and for stabilizing aqueous suspensions of minerals. |
