  1. Predicting Segmental Behavior of Polymers from their Chemical StructureAlexei P. Sokolov, University of Akron, DMR 0605784 We developed a qualitative concept that can: • Predict the temperature variations of segmental relaxation (fragility) from knowledge of polymeric chemical structure. It is based on the recent theoretical work [Dudowicz, et al., J.Chem.Phys. 123, 111102 (2005)] and emphasizes the importance of relative side group and backbone flexibilities (Fig.1). • Explain the “polymer specific” behavior that differentiate structural relaxation in many polymers from the relaxation in small molecules. • Describe the variations of the segmental dynamics with molecular weight.

  2. Predicting Segmental Behavior of Polymers from their Chemical StructureAlexei P. Sokolov, University of Akron, DMR 0605784 Broader Impact: The developed concept might be very useful in design of new polymeric materials for various applications, including energy and bio-medical fields. Education: Under this grant, two students, J.H.Roh and B. Begen have completed their PhD. Three more PhD students, K. Kumar, L. Hong, and A. Agapov and a post graduate student S. Pawlus have been actively involved in the research. Outreach: Our group is involved in teaching school students through the Science Fair and the University of Akron Math and Science Upward Bound Program for disadvantaged students. We also work with the Akron Global Polymer Academy to assist K-12 science instruction via distance learning and personal interaction. Dr. Sokolov works with students from Copley-Fairlawn Middle school (CFMS), in particular, helping them with preparation for Science Olympiad. The team from CFMS became 3rd in the State of Ohio in 2008. This is the best achievements ever for this school. The Science Olympiad Team from the Copley-Fairlawn Middle School became 3rd in the State of Ohio competition in 2008. The picture shows the team after the State award ceremony.
