Synthesis and Applications of Novel Silicone Materials: A 3M Innovation Story
3M sells more than 55,000 products across a wide array of industries. Many of these products are successful due to their unique chemical and materials properties, and as such, synthetic chemistry is a powerful tool to fuel our company’s culture of innovation. More than 15 years ago, we discovered a class of drug molecules, the 4-aminopyrazoloquinolines, which afforded pre-clinical candidates for melanoma and hepatitis. Then, motivated by unforeseen events, and as proof that the world around us is never static, we directed our attention to polymer synthesis. Drawing on the chemistry of our pharmaceutical compounds, a novel class of segmented silicone block copolymers was discovered. These new materials offer differentiated performance in applications ranging from optical films to adhesives. This talk will describe the synthesis and properties of the aforementioned material sets and reinforce that synthetic chemistry is a powerful tool to solve important problems in both the biological and materials sciences.

About David Hays
David Hays, Ph.D., received his Bachelor of Science degree in chemistry in 1993 from the University of Illinois. During his undergraduate years, he performed research at Eastman Kodak on photoconductive materials for photocopiers and studied phosphate-based cements in the laboratories of Professor Walter Klemperer. In addition, Hays worked under the direction of Professor Scott Denmark on the development of dioxirane-mediated epoxidations of olefins. He completed his doctorate in organic chemistry at the Massachusetts Institute of Technology in 1998, working under the direction of Professor Greg Fu. His dissertation work focused on the application of organotin reagents to catalytic free radical transformations.
Hays moved to St. Paul, MN, in 1998 and joined the Adhesive Technologies Center at the 3M Company where he studied mechanistic aspects of structural bonding at low energy interfaces and the synthesis of conjugated polymers for use in colorimetric biological sensors. In 2002, Hays moved to 3M’s Pharmaceutical Division where he developed novel small molecule toll-like receptor agonists targeting a variety of disease states such as melanoma and hepatitis C. Between 2006 and 2008, he worked in 3M’s Display and Graphics Film Lab where he developed new polymers for multilayer optical film (MOF) reflectors. He then moved to 3M’s Materials Resource Division where he currently works on the discovery, chemical process development, and manufacturing of new materials with business importance to 3M, most notably within the family of novel silicone polymers.
