Abstract

A composition that is a reaction product of two or three moieties. The first moiety (A) is a nonpolymeric, functional moiety that can adsorb onto a particle. The second required moiety (C) is a linear or branched water soluble, nonionic polymer that is capable of providing dispersing capability. A third moiety (B), if present, is a nonpolymeric moiety disposed between the first and second moiety, to connect the first and second moieties.
