Rheological Methods for Determining Molecular Weight & Molecular Weight Distribution 17/4/2008
Abstract
The molecular weight and molecular weight distribution (MWD) of linear polymers can be derived by using rheological methods. The mechanical excitation of polymers leads to a characteristic response of the material depending on its macromolecular structure. Using the HAAKE RheoWin software with optional tools like TTS (Time Temperature Superposition), Spectra and MWD (Molecular Weight Distribution) master curves, relaxation time spectra and molecular weight distributions can be easily generated out of dynamic tests (Oscillation frequency sweeps). Practical results are presented and discussed in this application report. Read More »
