    Photopolymerization is one of the most rapidly expanding processes for materials production with more than 15% annual growth projected for the next several years. Ultimately, the growth in applications of photopolymerization is driven by the advantages afforded by the use of light, rather than heat, to drive the conversion of monomer to polymer. These advantages include: solvent-free formulations; very high reaction rates at room temperature; spatial control of the polymerization; low energy input; and chemical versatility. Due to this unique set of advantages, photopolymerizations have gained prominence in recent years for the solvent-free curing of polymer films as well as emerging applications in dental materials, conformal coatings, electronic and optical materials, and rapid prototyping of three dimensional objects.

    The tremendous growth in applications of photopolymerizations has out-paced the supply of scientists and engineers trained in the fundamentals of photopolymerization systems. The goal of this shortcourse is to address this problem by providing the participants with an understanding of the fundamentals of photopolymerization systems.

Shortcourse Lecturers

Dr. Mike J. Idacavage received his B.S. (Chemistry) from Drexel University in 1975 and his Ph.D. from Syracuse University in 1979 (Organometallic Chemistry). He joined Eastman Chemicals in 1979, serving at different times as Development Chemist, Manufacturing Support and Technical Service for Coatings. Dr. Idacavage's work in the area of photopolymerizations started at Eastman Chemicals with the establishment of a photopolymer lab in 1985. From 1986 to 1996, he held the position initially of Technical Manager and then Research Director at NAPP Systems, a leading supplier of photopolymer printing plates. In 1996, he left NAPP to join UCB Chemicals a supplier of Monomers and Oligomers. Currently, Dr. Idacavage is Vice President of Research & Technology with responsibility for the Radiation Curing, Powders, Composites, PSA, Analytical and Engineering technologies.

Born in Madras, India, Andy Kannurpatti obtained his undergraduate degree in Chemical Engineering at the Indian Institute of Technology, Madras. Subsequently, he moved to the United States in 1992 to pursue a Ph.D. in Chemical Engineering at the University of Colorado. His doctoral thesis work involved a comprehensive study of living radical photopolymerizations and the evolution of structure and properties in photocrosslinked networks. As a graduate student, Kannurpatti also worked on various applications of photopolymerizations - ranging from nonlinear optics to dentistry. This diverse experience prepared him for a technical position in DuPont with the Cyrel® Packaging Graphics business. Kannurpatti has been in the R&D group for four years now and has been contributing to the development of new products and technologies as well as research in polymer processing. His current assignment includes being the Technical Leader for the Cyrel® Digital FAST System development. Kannurpatti has been named as an inventor on 7 patent applications, has authored 21 technical reports and publications, and has presented his work at various meetings and conferences.

Dr. Eric W. Nelson received his B.S. in Chemistry from Alma College in 1991 and his Ph.D. in Chemical Engineering from Michigan State University in 1995. His graduate thesis dealt with the kinetic and mechanisms of cationic photopolymerization of vinyl ethers. These fast kinetics were investigated with spectroscopic characterization techniques, including the use of novel fluorescence and Raman techniques. Since graduation, he has been employed with 3M Company. His initial position was in the Corporate Process Technology Center in the UV Processing group. This involved formulation and process optimization of both free radical and cationic photopolymerization systems. Since January 2000, he has been employed in the Construction and Home Improvements Markets division of 3M. He has published numerous papers, and has given several invited talks and presentations at professional meetings.

Dr. Alec B. Scranton received his B.S. from the University of Iowa in 1984 and his Ph.D. from Purdue University in 1990, both in Chemical Engineering. He served on the faculty at Michigan State University 1990 - 2000. In January of 2000 he joined the faculty at the University of Iowa as the Chair of the Department of Chemical Engineering and the Director of the Center for Photopolymerization. Dr. Scranton's research interests include, kinetic and mechanisms of cationic and free radical photopolymerizations, novel applications of light-induced reactions, polymer networks, and reversible emulsifiers. He has published more than sixty papers, has been granted seven patents, and has given numerous invited talks and presentations at professional meetings

Dr. Christopher N. Bowman received both his B.S. and his Ph.D. in Chemical Engineering from Purdue University in 1988 and 1991, respectively. Since January of 1992 he has served on the faculty in the Department of Chemical Engineering at the University of Colorado where he is now Professor, Gillespie Faculty Fellow, and co-Director of the Photopolymerization Center. Professor Bowman’s research interests focus on fundamental characterization of and development of new applications and monomers for free radical photopolymerization reactions, focusing in particular on how physical and chemical properties affect free radical photopolymerizations kinetics. He has published more than one hundred papers, has given numerous invited talks and presentations at professional meetings, and has been awarded outstanding young investigator awards by the American Institute of Chemical Engineering, the American Society for Engineering Education, and the Materials Research Society.
