[3] 80% is the result of the following calculation: pyrolysis residue minus the carbon black concentration in the compound gives the quantity which is then calculated as a percentage of the carbon black content. Thus if a 1% (mass%) carbon black compound has a residue of 1.8%, this means an 80% excess.
[4] Identifiable by "melt fracture" (roughened, often fish-scale-like surface)
[5] Weighing precision 1/10 g
[6] Term describing the layer of plastic that wraps around the roller.
[7] It was only possible to analyse one series of measurements, as the wax migrated to the surface, thereby distorting the viscosities in the subsequent measurements. Cf. sub-section 3.4.
