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

BS ISO 1628-5-1998 发布历史

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 polyethylene terephthalate) (PET), poly(butylene terephthalate) (PBT). poly- (cyclohexylenedimethylene terephthalate) (PCT), and polyethylene 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.
