  • Halogen-free resin composition with high frequency dielectric property, and prepreg and laminate made therefrom
    Patent number: 8124674
    Abstract: The present invention relates to a halogen-free resin composition with high frequency dielectric property, and a prepreg and a laminate made therefrom. The halogen-free resin composition with high frequency dielectric property comprises, calculating according to the parts by weight of organic solids: (A) 10-50 parts by weight of copolymer of styrene-maleic anhydride; (B) 10-50 parts by weight of at least one compound having dihydrobenzoxazine ring; (C) 10-50 parts by weight of at least one polyepoxide; (D) 5-30 parts by weight of at least one phosphorus-containing flame retardant. Prepregs and laminates made from the resin composition have low dielectric constant, low dielectric dissipation factor, high glass transition temperature, high heat resistance, low moisture adsorption, and the technological operation is simple.
