Real‐time FTIR conversion degree–time profiles considering the radical polymerizable acrylate group of M1 with the conversion degree of cationic polymerizable groups comprising the respective epoxide and oxetane monomers M2 a and M4 a, respectively. NIR‐sensitized photopolymerization was pursued at 805 nm investigated by the initiator combination of 1 d and 2 d ([1 d]=6×10⁻³ mmol g⁻¹, [2 d]=3.8×10⁻² mmol g⁻¹). For comparison, polymerization was pursued in the neat monomers M1, M2 a, and M4 a and mixtures of M1/M2 a and M1/M4 a. Intensity of the 805 nm LED device was 1.2 W cm⁻².
