SUMMARY
The viscosity of polymers, such as microcrystalline cellulose, is directly related to their degree of polymerization, meaning that larger polymers exhibit higher viscosity. This relationship is quantified through the Mark–Houwink equation, which establishes a correlation between molecular weight and viscosity for specific polymer-solvent pairs. While the discussion raises questions about the viscosity of non-polymers, such as isopropanol compared to ethanol, it is important to note that viscosity is influenced by multiple factors beyond molecular weight, and experimental determination is essential for accurate comparisons.
