Abstract:
The water content of hydrophilic polymers is a fundamental property that regulates their performance. Herein, we report a new technique for optically imaging the water content of hydrophilic polymers both in static and dynamic evolution during swelling, based on mapping the interfacial refractive index of hydrophilic polymers with label-free total internal reflection microscopy.

Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
The extent of the...
