Abstract
A resin composition includes a prepolymer and an additive, wherein: the prepolymer is prepared from a mixture subjected to a prepolymerization reaction, and the mixture includes 100 parts by weight of a maleimide resin, 15 to 30 parts by weight of a siloxane compound and 4 to 16 parts by weight of a diamine compound; the maleimide resin includes bisphenol A diphenyl ether bismaleimide, 3,3′-dimethyl-5,5′-diethyl-4,4′-diphenylmethane bismaleimide or a combination thereof; the siloxane compound includes a compound of Formula (I), wherein n is an integer of 5 to 40; and the diamine compound includes a compound of Formula (II) or Formula (III). The resin composition is made by using a preparation method. The resin composition may be used to make various articles, such as a prepreg, a resin film, a laminate or a printed circuit board.
