Beschreibung
Zusammenfassung:Ethylenically unsaturated blocked aromatic diisocyanates are prepared which readily polymerized to form homopolymers and interpolymers with copolymerizable vinylidene monomers. Polymers can be prepared via emulsion polymerization, and exhibit excellent stability to hydrolysis when stored in latex form. The polymers cure at temperatures as low as 80.degree.C., and under acidic, neutral, or basic pH conditions. Homopolymers and interpolymers of the defined diisocyanates are useful as adhesives, and interpolymers of the ethylenically unsaturated blocked aromatic diisocyanates with acrylate monomers are particularly useful as binders for nonwoven fibers.
