Gel permeation chromatograms obtained for PEG₁₁₃-PHPMA₂₀₀ diblock copolymer syntheses conducted at various temperatures using RAFT aqueous dispersion polymerization at 10% w/w solids at a [PEG₁₁₃-DB]/[initiator] molar ratio of 3.0. Suitable free radical initiators were selected for a given reaction temperature: ACVA was used at 70 °C, AIBA was employed at 55 and 60 °C, and AIPD was utilized at 50 and 45 °C (see main text for details).
