标准名称

ISO 1628-2 Plastics; determination of viscosity number and limiting viscosity number; part 2: poly(vinyl chloride) resins

ISO 1628-2塑料.粘度数和特性粘度数的测定.第2部分:聚(氯乙烯)树脂

适用范围

This part of ISO 1628 specifies conditions for the determination of the reduced viscosity (also known as viscosity number) and K-value of PVC resins. It is applicable to resins in powder form which consist of homopolymers of the monomer vinyl chloride and copolymers, terpolymers, etc., of vinyl chloride with one or more other monomers, but where vinyl chloride is the main constituent. The resins may contain small amounts of unpolymerized substances (e.g. emulsifying or suspending agents, catalyst residues, etc.) and other substances added during the course of the polymerization.
