Wet adhesion monomers with ureido functionality and polymers prepared therefrom

摘要

Compounds containing a ureido group which are useful in preparing dispersions of polymers having good wet adhesion properties and low volatility. Compounds having the formula: <IMAGE> where R1 is H or an alkyl group, R2 is alkylene optionally interrupted with one or more ether oxygen atoms and A is H or a residue of an active hydrogen reactive compound are useful for incorporating ureido and optionally nitrile functionality into polymers and as precursors to amino compounds prepared by reduction of the nitrile group thereof. Compounds having the formula: <IMAGE> where B is defined as for A and the same or different than A are also disclosed. The disclosed compounds have use as chain extending or terminating monomers for polyurethane dispersions when one or both of A and B are H and, when one of A and has ethylenic unsaturation, as wet adhesion monomers in dispersions of free radically polymerized polymers of unsaturated monomers.
