Effects of the Addition of Ortho- and Para-NH₂ Substituted Tetraphenylporphyrins on the Structure of Nylon 66

Table 1

Weight % of carbon, oxygen, and cobalt evaluated by EDS on the surface of Ny 66-Co-𝑜-NH₂ and Ny 66-Co-𝑝-NH₂ samples.

Sample	% w/w; Carbon	% w/w; Oxygen	% w/w; Cobalt	Monomer units (𝑛)	Number of units; bilateral chain*
Ny 66-Co-𝑜-NH2	83.24	16.67	0.09	376	94
Ny 66-Co-𝑝-NH2	77.57	21.33	0.10	312	78

∗Lateral chains are formed by 𝑎, 𝑏, 𝑐, or 𝑑 units rendering a total of 𝑛 units in each porphyrin.
