However, in conjugated heteroaromatic alternating polymers, such as poly(furanqunoxaline)s, and poly(phenylene-1,3,4-oxadiazole)s, a main peak with a shoulder in the cyclic voltammogram has been observed (44), (45).
Harrel designed the AP-600 turnkey extrusion system specifically for alternating polymers. Harrel offers a complete two-component extrusion system at a 20-25% premium above a conventional coextrusion line.
