Nanotechnology refers to the research and development of materials that contain structures or features that have at least one length scale ranging from molecular to approximately 100 nm, and which exhibit improved or novel properties that are the direct result of their small size. These novel properties result from the tremendous amount of surface area that can occur between phases and/or confinement effects.1-3 Recently, Rohm and Haas has been investigating unique polymer/clay nanocomposites based on pressure-sensitive adhesives. These nanocomposites display unusual cohesive strength and high temperature resistance properties without overly compromising the pressure-sensitive nature of the latex. A variety of synthetic techniques have been developed that result in stable latexes with clay in or adhered to the polymer particle. The emulsion polymer/clay nanocomposites have different (and advantageous) properties relative to the emulsion polymers alone, and can be produced at a commercially viable cost.
