Abstract

Rheological Gel Point measurements may incur errors in the case of rapid gelling systemsdue to the limitations of multiple frequency oscillatory shear techniques such as frequency sweeps and Fourier Transform Mechanical Spectroscopy, FTMS. These limitations are associated with sample mutation and da...
