塑料 使用毛细管粘度计测定聚合物稀溶液粘度 第5部分：热塑性均聚和共聚型聚酯(TP)
Application Summary AI generated
This standard specifies a method for determining the viscosity of thermoplastic polyester (TP) homopolymers and copolymers in dilute solution using capillary viscometers. It is applied in the plastics industry for quality control and material characterization, specifically to measure the intrinsic viscosity of polyesters like PET or PBT used in fibers, bottles, and engineering plastics. The test results help assess polymer molecular weight and processing behavior.
