The polymerisation of N ‐acryloylmorpholine in water is reported utilising Cu(0)‐mediated living radical polymerisation (SET‐LRP). The inherent instability of [Cu I (Me 6 ‐Tren)Br] in aqueous solution is exploited via rapid disproportionation to prepare Cu(0) particles and [Cu II (Me 6 ‐Tren)Br 2 ] in situ prior to addition of monomer and initiator. Quantitative conversion is attained within 30 min for various degrees of polymerisation (DP n = 20–640) with SEC showing symmetrical narrow molecular weight distributions ( Đ < 1.18) in all cases. Optimised conditions are subsequently applied for the preparation of a diblock copolymer poly(NIPAm)‐ b ‐( N ‐acryloylmorpholine), illustrating the versatility of this approach.
