Surface active polycarbodiimides
First Claim
1. A surface-active polycarbodiimide of the formula
wherein R is a residue of a hydrophobic organic compound containing at least two carbodiimide groups;
R'"'"' is a residue of an organic compound having a hydrophilic segment and at least one functional group capable of reacting with a carbodiimide group; and
X is a group formed by the reaction of a said carbodiimide group with a said functional group;
wherein R'"'"' is a residue of a hydroxyl-containing poly(alkylene oxide)-based surfactant and wherein the poly(alkylene oxide)-based surfactant is alkoxy-capped.

Abstract
Disclosed are surface-active polycarbodiimides containing a hydrophilic portion and a hydrophobic portion joined through the reaction of a carbodiimide group with a reactive functional group. The surface-active polycarbodiimides may be linear or branched, monodisperse or polydisperse, but preferably are of the branched, monodisperse type. The surface-active polycarbodiimides are useful as surfactants, and are particularly useful as emulsifiers in cross-linkable, carboxyl-containing resin systems, such as aqueous latexes.
