The thermoresponsive copolymer P(MEO2MA-co-OEGMA500) was successfully prepared using a novel photopolymerization procedure. The synthesis was carried out using a user-friendly method with a few ppm of a photoredox iridium-based catalyst. Monomer conversions higher than 50% were achieved in less than 1 h of synthesis showing a faster polymerization rate when compared to the traditional Cu-based ATRP synthesis. The photochemically controlled method here described provides true control over polymer structure, architecture, and properties. Furthermore, the polymer showed no toxicity on four mammalian cell lines at the highest concentration tested (0.4 mg/ml).
