Branching Analysis of Polyethylenes with Cirrus Multi Detector Software

The presence of long chain branching (over 6 carbons in length) in polyolefins strongly influences physical properties such as melt viscosity and mechanical strength. The distribution chain branches in polyolefins is determined by the polymerization mechanism and there is significant interest in the production of materials with well defined and characterized molecular weight and branching distributions for specific applications. Polymer Laboratories' latest technical bulletin describes the analysis of three samples of polyethylene with the PL-GPC 220 by GPC/Viscometry.
