GB/T 1632.5-2008 "Plastics - Determination of the viscosity of polymers in dilute solution using capillary viscometers - Part 5 : Thermoplastic polyester(TP) homopolymers and copolymers"

This standard is the fifth part of the GB/T 1632 series of standards. It was first published and modified to adopt ISO 1628-5:1998. The standard specifies the method for determining the viscosity of dilute solutions of thermal plasticity polyesters (such as PET, PBT, PCT, PEN, etc.) in specific solvents. It is suitable for the determination of molecular weight of homopolymer and copolymer polyesters. The viscosity determination adopts the general method specified in GB/T 1632.1-2008 and follows the test conditions of this part.
