The ring-opened metathesis copolymerization of cyclopentene with cyclooctene by an electrochemically generated WCl6-based catalyst has been prepared and C-13 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 degrees C. Homopolymerization of cyclopentene is also reported to compare with copolymers produced in this work.
