    • The "non-functionalized" PCOE is made of and also of linear polymers which may arise from the direct initiation of ROMP by G2, especially when the CTA is not reacting (entries 1 and 11). Linear products may also be formed in small amounts through the eventual decomposition (during workup) of the Ru-activated linear polymer chain such as II/III (Scheme 1)

    • GLC and NMR analyses did not reveal the presence of residual DMAP, which is used in the synthesis of CTAs, 3-OEt or isom-4. Indeed, DMAP is known to inhibit Ru-based metathesis catalysts: purposely added DMAP (1 equiv. [Ru]) lowers the reactivity of the catalyst 5 times, while the ROMP reaction was entirely inhibited using 2 or more equiv. of DMAP; see
