Polymer names are determined according to the average degree of polymerisation (DP) determined by 1H-NMR end-group analysis in methanol-d4.
[M] : [CTA] indicates the ratio between monomers (M) and the chain transfer agents (CTA).
Monomer conversion (%) calculated by comparing the integration values of the monomer signals with those of the corresponding signals of the polymer.
M n, NMR was calculated by end-group analysis by comparing the integrations of the –CH3 signals (δ 0.92 ppm) of dodecyl end-group with those of the corresponding signals of the polymer backbone.
M n and ĐM values calculated from PMMA standards using 5 mM NH4BF4 in DMF as the eluent.
