Dissolution is carried out using a reaction block with stirring and heating at deg. In addition we may use third party services such d463 Google Analytics that collect, monitor and analyse this data. Highly crystalline forms of PET that are not soluble in this solvent mixture will require a different procedure.

Dilute Solution Viscosity is used as an indication of the molecular weight of polymers. The liquid is then brought above the upper graduation mark on the viscometer. Read more about the individual cookies we use and how to recognise them by clicking Cookie Policy.

E4603 is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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. The test method requires a 0. Specific hazards statements are given in Section 8.
