Description	Poly(carboxybetaine)s (poly(CB)s) are unique, emerging as the only ultra-low fouling materials allowing the preparation of biosensors, fouling resistant nanoparticles, and non-adhesive surfaces for bacteria. Poly(CB)s have been prepared via atom transfer radical polymerization, however no control was achieved. Herein, the first successful living/controlled reversible addition fragmentation transfer polymerization of (3-methacryloylamino-propyl)-(2-carboxy-ethyl)-dimethyl-ammonium in acetate buffer (pH 5.2) at 70 and 37 °C is reported. The polymerization afforded very high molecular weight polymers (250 000 g mol1 in less than 6 h) with low PDI (<1.3) at 70 °C. The polymerization was additionally carried out at 37 °C achieving yet lower PDIs (1.06 PDI 1.15) even at 90% conversion, demonstrating the suitability of the polymerization conditions for bioconjugate grafting. Block copolymerization from biologically relevant poly[HPMA] macroCTAs was additionally performed.
