The ratio of the natural logarithm of the relative viscosity to the mass concentration of the polymer.
You can instruct your browser to refuse all cookies or to indicate when a cookie is being sent. The ratio of the difference between the viscosities of solution and solvent to the viscosity of the solvent. C using the same 1B size of suspended-level Ubbelohde type viscometer for both measurements.
The method requires that three successive flow times are obtained within 0. Solvent and solution flow times are measured at 30 deg.
ISO also uses Type 1C Ubbelohde viscometer, rather than the 1B, and reports viscosity number, rather than inherent viscosity.
ASTM D4603 – 18
Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. The polymer is first weighed and then dissolved in an appropriate solvent. Highly crystalline forms of PET that are not soluble in this solvent mixture will require a asttm procedure.
