WebIntroduction. The polymer chain length in PET determines the molecular weight of the material and with it the physical properties that make PET such a useful packaging material. Intrinsic Viscosity (IV) is a measure of the polymers molecular weight and therefore reflects the material’s melting point, crystallinity and tensile strength. WebSep 7, 2024 · Eventually the viscosity gets so high that the polymer cannot be processed easily, establishing an upper molecular weight beyond which it is prohibitively expensive …

The viscosity … WebSep 12, 2024 · In this case, the relationship is described by the Mark-Houwink equation: (4.2.1) [ η] = K M α. In this equation, [η] is the intrinsic viscosity; that's the viscosity attributed to the solute, rather than the viscosity of the solvent itself. M is the molecular weight. K …
