摘　　要：In this study, a UV-curable polysiloxane methacrylate （PSMA） was synthesized by a one-step method. The reaction was catalyzed by chloroplatinic acid between polymethylhydrosiloxane （PMHS） and hydroxyethyl methacrylate （HEMA）, as proved by FTIR and ^1H-NMR. The preliminary results indicate that the obtained UV-cured PSMA film has very good thermal stability, excellent transparency and satisfactory tensile strength. Our work provides a simple but efficient way to prepare UV-curable PSMA, which may find potential applications in UV-curing optical fiber, metal and glass coating and other fields.In this study, a UV-curable polysiloxane methacrylate （PSMA） was synthesized by a one-step method.
