Abstract: This invention is directed to dense star polymers and to a process for producing dense star polymers. The star polymers of this invention have at least one core branch eminating from a core, each core branch having at least one terminal group provided that (1) the ratio of terminal groups to the core branches is greater than 1 : 1, (2) the density of terminal groups per unit volume in the polymer is at least 1.5 times that of conventional star polymer having similar core and monomeric moieties and a comparable molecular weight and number of core branches, each of such branches of the conventional star polymer bearing only one terminal group and (3) a molecular volume that is no more than 60 percent of the molecular volume of said conventional star polymer. Such star polymers are useful as demulsifiers for oil/water emulsions, wet strength agents in the manufacture of paper and agents for modifying viscosity in aqueous formulations such as paints.

Abstract: For preparing a polyether-dendrimer-alkali metal salt (a) a polyvalent core W(X) n wherein W is a polyvalent core atom which is covalently bonded to nX reactive terminal OH-groups (n≧2) is converted into its correponding alkali metal salt by reaction of the polyvalent core with alkali metal hydroxide or zero valence alkali metal, (b) the obtained salt is reacted with a molar excess of a partially protected multifunctional reagent T-(U) V m wherein U represents a multivalent moiety covalently bonded to m V protected moieties (m≧2) and to one T, a moiety capable of reacting with X to form W[(X'-T')U V m ] n , wherein X' and T' represent the residue of reaction between X and T, (c) the obtained first generation compound is activated by de-protecting it, (d) the activated compound is converted into alkali metal salt form by reaction with alkali metal hydroxide or zero valence alkali metal, and, if desired, (e) the alkali metal salt is reacted with further partially protected reagent T-U- V m to form the second generation protected dendrimer, (f) and steps (c) and (d) are repeated to provide higher generation dendrimer alkali metal salts.
