    • n(PBD) greater than or equal to 5 produced a successful CTA; in such cases, each polymer chain contained sufficient accessible olefins if we consider the inherent distribution of butadiene repeat units and the removal of 1,2-butadiene repeat units via hydrosilylation.

    • Although it seems plausible that the silyl-protected 1,2-PBD units could be removed during this reaction according to the cyclization route described by Watson and Wagener22 for the depolymerization of PBD, triethylsilyl peaks at 0.9 and 0.5 ppm were still observed in the 1H NMR spectrum. However, at an average of one branched 1,2-repeat unit per chain less than one branch per 1000 backbone carbons for compositions containing at least 37% PCOE, the effect on the crystallinity of the final PE product should be low, if not negligible
