Pentaethylenehexamine (abbreviated PEHA) is an organic amine. It is composed of five ethylene groups-CH 2 CH 2 - joined together in a chain by four secondary amine groups (-NH-) and terminated on each end by primary amine groups (-NH 2). Pentaethylenehexamine is a hexadentate ligand, owing to the Lewis basicity of the six amine groups. [3]

The z-average molar mass is the third moment or third power average molar mass, which is calculated by ¯ = The z-average molar mass can be determined with ultracentrifugation. The melt elasticity of a polymer is dependent on M z. [5]
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
