Following the series of Asian Polyolefin Workshops, APO 2005 in Nara of Japan, APO 2007 in Hangzhou of China, APO 2009 in Seoul of Korea and APO 2011 in Bangkok of Thailand, the APO 2013 will be held in Beijing, China, from 15th through 19th October, 2013. This workshop will provide a forum for Asian scientists and engineers in all aspects of polyolefin to exchange and cross-fertilize the currently progresses in both knowledge and technique. Its topics will focus on polyolefin multi-disciplinary subjects: Pre-catalysts (heterogeneous and homogeneous) and activators (Alkyl-aluminum reagents and beyond), Polymerization intermediates and mechanism, Characterizations and properties of precise polyolefin, Technical process from bench to commercial scale, New techniques such as computation and parallel reactor, etc. We cordially invite you to participate with presenting your new achievements. Please kindly return your Preliminary Registration in order for the Organizing Committee to select invited and oral speakers as well as posters. The abstracts should be prepared in English within A4 paper with 25 mm margin and submitted as the e-mail attached documents.
