East-Asian Polymer Conference was first held in Shanghai, 1995 to provide a platform for the world-wide polymercommunity, especially from East-Asia, to exchange and discuss new ideas and findings in Polymer Science and Technology. Following the success of the four conferences, the 5th conference(EAPC-5) is going to be host-ed by East China University of Science and Technology and it will be held on June 3-6,2008 in Shanghai, China. The scientific program of EAPC-5 will cover current topics and recent pro- gress in all areas of polymer science,including polymer che-mistry, polymer physics, polymer materials and applications. The organizing committee extends it cordial invitation to you for participating in EAPC-5. We will make ever efforts to maximize the interactions among the participants to facilitate scientific exchange and to foster potential research collaborations.
