The prepared emulsions were subjected to different techniques, including optical microscopy and
viscometry to characterize the emulsion and to investigate the coalescence.
To reach their findings, the researchers used several methods such as nuclear magnetic resonance (NMR), spectroscopy and infrared spectroscopy, dynamic light scattering, conductometry to measure the solutions' electric conductivity, and
viscometry to measure fluid viscosity.
The prior research [41] also found viscous heating and pressure dependence to be significant contributors to the variations in capillary
viscometry. As the polymer melt flows through the capillary, viscous dissipation results in melt temperature increases.
Materials and Methods: Thermogravimetric analysis and rotational
viscometry, which affect the process of the formation of carbopol, were taken.

viscometry measurements can be used, for example, in blending resins with differing molecular weights, or in reactive extrusion, as a quality-control tool or as a process-control input, notes Golba.
The unique features of the m-VROCi efficiently meet an established need in many industries for high shear rate
viscometry. With Malvern's support, industrial customers will now be able access the rheological data required to advance product and process performance in a highly effective way."
The prepared resin samples were characterized by using molecular weight determination
viscometry, field emission scanning electron microscopy (FESEM), and thermogravimetric analysis (TGA).
