Omfang

This part of ISO 1628 defines particular conditions for determinirrg the viscosity number and limiting viscosity number of polyethylenes and polypro-pylenes at 135 *C in dilute Solution. lt 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 viscosity number determined by this method may therefore be unreliable if the Sample contains fillers or other additives. NOTE 1 Viscosity number is also known as the Staudinger function (Jy) and limiting viscosity number as the Staudinger index (Jg).
