Abstract | Cited by

The nitroxide mediated copolymerization of 2-hydroxyethyl acrylate (HEA) and 2-methoxyethyl acrylate (MEA) is reported. The copolymerization kinetics followed the persistent radical model and revealed the formation of well-defined ideal random copolymers (rHEA = 0.93 ± 0.09; rMEA = 0.95 ± 0.09). SEC-ESI-MS proved the presence of both the initiation fragment and SG1 as chain ends of the polymers. The cloud point temperature of the copolymers increased from 5 °C and 60 °C with increasing HEA content from 0% to 70% and they are discussed in relation to both monomer and end-group structure.
