In this webinar you will learn:
The most discriminating structural property in polymers is probably missing in your GPC Analysis. Resins that seem nearly identical by a standard GPC analysis can only be fully differentiated when adding Short Chain Branching information.
Chemical Composition Distribution is a critical dimension for the study of the microstructure of polyolefins, but it is often overlooked because its impact is not widely known. This presentation will explain what Short Chain Branching Distribution is, why it is so relevant to understanding the microstructure of a resin, and how it can be obtained. Two approaches for analyzing the CCD will be presented, first by high-temperature GPC-IR, and then by the most powerful techniques based on crystallization and adsorption chromatography; TREF, CRYSTAF, CEF, and TGIC.
Alberto Ortin received a Master’s Degree in Electronics Engineering at the Polytechnic University of Valencia, Spain, and a Master’s Degree in Analytical Chemistry from the University of Valencia. He received his Ph.D. in Chemistry from the same University of Valencia in 2014.
He is now a scientist at Polymer Char, where he has accumulated 25 years of experience in the development of instruments, software, and detectors for different polyolefin characterization techniques, including GPC, TREF, and cross-fractionation. He has authored several papers on polyolefin separation methods at high temperature and is a major contributor to the technical program of the International Conference on Polyolefin Characterization.
