Abstract
A resin composition and an article made therefrom are provided. The resin composition includes: (A) 100 parts by weight of an unsaturated bond-containing polyphenylene ether resin; (B) 20 parts by weight to 150 parts by weight of a copolymer, the copolymer having a structural unit formed by a monomer of Formula (1) and a structural unit formed by a monomer of Formula (2), and the content of the structural unit formed by the monomer of Formula (2) in the copolymer is 55 wt % to 90 wt %; and (C) 10 parts by weight to 40 parts by weight of an unsaturated bond-containing crosslinking agent. 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 glass transition temperature, Z-axis ratio of thermal expansion, multi-layer board heat resistance, interconnect stress test, dissipation factor aging rate, temperature coefficient of dielectric constant, temperature coefficient of dissipation factor and branch-like pattern at laminate edges.
