Simplifying Entangled Polymer Synthesis
“The Viscotek 270max is critical to verifying this new method of polymerization,” explained Professor Rigoberto Advincula, Department of Chemistry, University of Houston. “These are high-molecular-weight polymers, and ring closure is a thermodynamically difficult reaction that must be done under dilute conditions. Using the triple detection offered by 270max, we were able to effectively characterize the molecular weight of our sample and detect the degree of ring closure versus the amount of non-closed polymer.”
The University of Houston’s initial success implies that it will be possible to synthesize superior knotted polymers for applications in coatings, lubricants and surface modifiers, among others. In terms of polymer theory, Professor Advincula’s team also plans to make catenated and knotted block co-polymers. The project has been funded by the National Science Foundation (USA).
The Viscotek 270max from Malvern Instruments is a complete, advanced, multidetector GPC/SEC system suitable for all macromolecular applications, particularly research. Further information can be found at www.malvern.com/viscotek.
