    Abstract: A resin composition includes 50 parts by weight of a vinyl-containing polyphenylene ether resin, 1 part by weight to 30 parts by weight of a styrene-butadiene-styrene block copolymer and 0.5 part by weight to 30 parts by weight of a zinc molybdate-covered silica, wherein the zinc molybdate-covered silica has a mass ratio of zinc molybdate to silica of between 1:9 and 2:8. The resin composition may be used to make various articles, such as a prepreg, a resin film, a laminate or a printed circuit board, and at least one of the following properties can be improved, including gel time stability, copper foil peeling strength, difference rate of dissipation factor and conductive anodic filament test.
