The First International Conference on Polyolefin Characterization (ICPC) held in Houston, Texas, in October 2006, was organized to fill the important industrial and academic need for a discussion forum on the characterization and fractionation techniques of polyolefins. These proceedings represent an excellent and up-to-date overview of recent advances in this important area, providing much information and facts that are not available elsewhere. The result is a collection of top quality contributions by experienced editors and international authors on such fields as separation and fractionation, high throughput processes, thermal and crystallinity analysis, spectroscopy and rheology. Equally of high interest for the polymer industry.
