In this study, a polymer blend with a salami structure with dimensions of several tens of microns was obtained by simultaneously polymerizing polymethacrylate and polyurethane. The methacrylate component of the polymer blend was co-polymerized with hydroxyethyl methacrylate (HEMA), which contains a hydroxyl group. The HEMA copolymerization increased the compatibility between the polyurethane and polymethacrylate regions. Consequently, the hard areas within the spherical domains decreased in size, accompanied by a decrease in the differences in composition and refractive index between regions.
