Data determined from their ¹³C NMR spectra using approaches described elsewhere;²⁵N_x^′ refers to the relative percentage of methyl, ethyl, propyl, butyl, amyl, and longer-chain branches.

Branching (% R) can be calculated with respect to the total ethylene units XδδCH₂PE present in the polymer: R (%) = N_M + N_E + N_P + N_B + N_A + N_M(1,4) + N_M(1,5) + N_M(1,6) + N_L + N_L(1,4); N_x refers to the results described in Tables S2–S9.

Expressed as per 1000 Cs.
