We developed impact-resistant, haze-free poly(methyl methacrylate) (PMMA) by photopolymerization-induced microphase separation. Upon irradiation, a polymerization mixture transforms into a transparent monolithic solid. A nanoscopic bicontinuous morphology of glassy PMMA with rubbery and cross-linked polymer domains retains transparency and dimension stability even at high temperatures. 3D printing via direct ink writing demonstrates the potential of the developed material for advanced optical and structural applications.
