Abstract: Novel monomer chemistries undergo polymerization under ambient environment in water. This attribute provides a powerful and simple new approach to enhance the properties of emulsion polymers, waterborne coatings and related applications. Direct emulsion polymerization and polymerization from latex particle surfaces was demonstrated. This strategy was employed to introduce high functional group densities to the latex particles, providing UV and free radical crosslinking capability to the latexes and coatings. Systematic studies were conducted to map thermal properties, surface morphology, crosslinking density and mechanical properties of the resulting coatings. Rapid UV curing and high crosslinking densities enable the synthesis of high-performance coatings based on very simple in-situ latex modification. This study provides a simple, new, in-situ (one pot) and readily scalable chemistry and methodology to significantly enhance performance of emulsion polymers, latex systems and resulting coatings and other applications.
