Resumen:

This part of EN ISO 15526 establishes a system of designation for polyketone (PK) moulding and extrusion materials which may be used as the basis for specifications. Polyketone polymer chains are built up from regularly alternatingolefinic units and keto groups. The olefinic units may be essentially all ethylene,or they may be, e. g., randomly distributed ethylene and propylene, butene or hexene.
