Polyalkylene glycol terminated poly-carbodiimides, and process for forming same

Abstract

An aqueous solution includes a polyalkylene glycol terminated poly-carbodiimide of formula 1: where: R1 is an aliphatic group from about 5 to about 12 carbon atoms, an isosorbide moiety, a 1,3-furan moiety, an L-lysine alkyl ester moiety, a rosin moiety, a cycloaliphatic unsaturated moiety, or a cardanol moiety; R2 is hydrogen or a methyl group; R3 is a methyl, ethyl, or propyl moeity; and n and m are integers and are each independently between 1 and about 30. The solution is optically clear.

Dependencies are inferred from the claim text.
