Polyphenylene oxide resin, method of preparing polyphenylene oxide resin, polyphenylene oxide prepolymer and resin composition

摘要

A polyphenylene oxide resin belongs to a polymerized and/or modified thermosetting polyphenylene oxide resin, having a structure represented by formula (I):; ;The polymerized and/or modified thermosetting polyphenylene oxide resin has better flame retardancy, thermal resistance, dielectric constant, dissipation factor, toughness, reactivity, viscosity and solubility. Therefore, the polyphenylene oxide resin is suitable for producing prepregs, resin films, laminates, printed circuit boards and other articles. A method of preparing polyphenylene oxide resins, a prepolymer thereof and a resin composition containing the polyphenylene oxide resin are also provided.
