PLASTICS - DETERMINATION OF THE VISCOSITY OF POLYMERS IN DILUTE SOLUTION USING CAPILLARY VISCOMETERS - PART 5: THERMOPLASTIC POLYESTER (TP) HOMOPOLYMERS AND COPOLYMERS (ISO 1628-5:1998, IDT)
MS ISO 1628-5:2008
Status : Original
Format : PDF

This Malaysian Standard 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 ....Read more 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 specifiedsolvents under the specified conditions.

The viscosity number is determined by the general procedure specified in ISO 1628-1, observing theparticular 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.

PLASTICS - DETERMINATION OF THE VISCOSITY OF POLYMERS IN DILUTE SOLUTION USING CAPILLARY VISCOMETERS - PART 3: POLYETHYLENES AND POLYPROPYLENES (ISO 1628-3:2001, IDT)
MS ISO 1628-3:2008

This Malaysian Standard defines particular conditions for determining the reduced viscosity (also known as viscosity number) and intrinsic viscosity of polyethylenes and polypropylenes at 135 °C in d ....Read more ilute solution. It is applicable to low, medium and high-density polyethylenes and to a wide range of polypropylenes, including pure isotactic, stereoblock and atactic polymers.

The viscosity of polymer solutions may be affected by additives present in the sample. The value of a reduced viscosity determined by this method may therefore be unreliable if the sample contains fillers or other additives.

NOTE: Reduced viscosity is also known as the Staudinger function (Jv) and intrinsic viscosity as the Staudinger index (Jg).
