A styryl siloxy polyphenylene ether resin, a preparation method therefor and an application thereof. The styryl siloxy polyphenylene ether resin is obtained by introducing styryl groups and siloxy groups into polyphenylene end groups by means of a simple synthesis method. The resin combines low dielectric property of curing of styryl groups and heat resistance, weather resistance, flame retardancy, dielectric property, and low water absorption of siloxy groups, thereby making better use of the application advantages of polyphenylene ether resins in copper clad laminates and providing excellent dielectric property, moist-heat resistance and heat resistance required by a high-frequency and high-speed copper clad laminate. |
