Abstract The ring‐opened metathesis copolymerization of cyclopentene with cyclooctene by an electrochemically generated WCl 6 ‐based catalyst has been prepared and 13 C NMR spectroscopy used to analyse in detail the nature of the homo‐ and hetero‐dyad units. This copolymer was characterized by gel‐permeation chromatography ( M n = 12 900, PDI= 2.2) and differential scanning calorimetry analysis. The glass‐transition temperature T g of the copolymer was −18.7 °C. Homopolymerization of cyclopentene is also reported to compare with copolymers produced in this work.
