Determined by ¹H-NMR.

Theoretical number-average molecular weight/degree of polymerization determined from conversion (¹H-NMR) and [M]:[CTA].

Number-average molecular weight/degree of polymerization/polydispersity from DMF SEC relative to PMMA standards.

Number-average molecular weight/degree of polymerization determined from ¹H-NMR spectroscopy from comparison of the RAFT agent end group to the -CH₂ backbone peaks.

Number-average molecular weight/degree of polymerization/polydispersity determined from DMF SEC after post-polymerization modification with 2-hydroxypropylamine to yield poly(2-hydroxypropyl methacrylamide).

Monomer to initiator ratio used was 800 : 1.
