Abstract
What is ISO 1628-2 about?
ISO 1628 is a series on plastics. Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as the main ingredient. ISO 1628-2 specifies conditions for the determination of the reduced viscosity (also known as viscosity number) and K- value of PVC resins. ISO 1628-2 applies to resins in powder form which consist of homo-polymers 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 lesser amounts of unpolymerized substances (e.g., emulsifying or suspending agents, catalyst residues, etc.) and other substances added during the polymerization. <span data-ccp-props='{"134233279":true,"201341983":0,"335551550":6,"335551620":6,"335559739":160,"335559740":264}' da...
