Abstract (en)
[origin: WO2022136292A1] The invention relates to polymers that have a dispersity of less than 1.4 and that can be obtained by irradiating a mixture of radically polymerizable monomers, cyanins as sensitizers, iron(III) compounds, alkyl bromides, and optionally ATRP starters with the aid of an NIR source which emits light in the range of approximately 700 to approximately 1200 nm.
