30 April, 2026 Molecular Weight Distribution in Polymers Averages, Dispersity, and How to Calculate them
19 February, 2026 Intrinsic Viscosity in Polymers: Definition, Measurement, and Why It Matters Intrinsic viscosity is a measure of a polymer’s ability to increase the viscosity of a solvent when dissolved at very low concentration. It is a critical parameter used to determine the molecular weight and size of polymer chains, providing a direct snapshot of the material’s structural integrity and quality. In practical terms, intrinsic viscosity helps manufacturers monitor product performance, detect degradation, and maintain batch-to-batch stability.
