Abstract Solvent‐free photopolymerization of vinyl monomers to produce high modulus materials with applications in 3D printing and photoswitchable is demonstrated. Polymerizable eutectic (PE) mixtures are prepared by simply heating stirring various molar ratios N ‐isopropylacrylamide (NIPAM), acrylamide (AAm) 2‐hydroxyethyl methacrylate (HEMA). The structural thermal properties the resulting evaluated 1D 2D NMR spectroscopy as well differential scanning calorimetry (DSC) thermogravimetric analysis (TGA). UV photocuring kinetics PE via situ photo‐DSC photorheology measurements. cure rapidly display storage moduli that orders magnitude greater than equivalent copolymers cured an aqueous medium. versatility these systems demonstrated through addition a spiropyran acrylate monomer, applying formulation stereolithography (SLA)‐based resin. Due hydrogen‐bonding network systems, resin possible absence crosslinkers. RAFT agent reduce average polymer chain length enables which retain their shape can be dissolved on demand appropriate solvents.
