ISO 1628-5:1998

Plastics - Determination of the viscosity of polymers in dilute solution using capillary viscometers - Part 5: Thermoplastic polyester (TP) homopolymers and copolymers

PUBLISH DATE 1998
ISO 1628-5:1998

This part of ISO 1628 specifies a method for the determination of the viscosity number (also referred to as “reduced viscosity”) of dilute solutions of thermoplastic polyesters (TPs) in certain specified solvents.

The method is applicable to:

  • poly(ethylene terephthalate) (PET),
  • poly(butylene terephthalate) (PBT),
  • poly(cyclohexylenedimethylene terephthalate) (PCT), and
  • poly(ethylene naphthalate) (PEN),
as well as to copolyesters and other polyesters, defined in ISO 7792-1, that are soluble in one of the specified solvents under the specified conditions.

The viscosity number is determined by the general procedure specified in ISO 1628-1, observing the particular conditions specified in this part of ISO 1628.

The determination of the viscosity number of a thermoplastic polyester provides a measure of the relative molecular mass of the polymer.
