Glassy polymers such as poly(methyl methacrylate) (PMMA) typically exploit rubbery domains to enhance toughness and impact strength, but maintaining transparency over a wide temperature range is challenging due to refractive index mismatches with temperature changes. Here, we demonstrate a strategy using photopolymerization-induced microphase separation (PIMS) to create transparent, temperature-resistant nanostructured polymers. Using poly(methyl methacrylate) (PMMA), the polymerization mixture converts into a cross-linked block polymer material. This process results in a bicontinuous nanostructure with PMMA and cross-linked rubbery microdomains, which form spontaneously during in situ polymerization. These PIMS materials retain transparency at high temperature and high temperature resistant. We also present the ability to 3D print these nanostructured materials through digital light processing.
