Effect of Acrylate Loading and Structure on the Phase Morphology and Thermal Stability of Silane-Functionalized Polyurethane Acrylates

In this study, propylene glycol-cored silane-functionalized polyurethane acrylate (SiFPU) hybrid networks were synthesized via a three-step route combining prepolymer synthesis and thiol–ene photoclick chemistry to yield a semi-interpenetrating polymer network (semi-IPN) architecture. The research examined how the structure and concentration (26 mass
