1. An article comprising a chemically crosslinked product of a resin composition, wherein the article comprises a prepreg, a resin film, a laminate, or a printed circuit board;
wherein the resin composition, based on 100 parts by weight of a maleimide resin, comprises:
(A) 1 part by weight to 15 parts by weight of a core-shell rubber;
(B) 5 parts by weight to 35 parts by weight of a vinyl-containing benzoxazine resin; and
(C) 100 parts by weight of the maleimide resin,
the core-shell rubber having a core-shell ratio of 6.0:4.0 to 9.5:0.5;
wherein the core-shell rubber comprises styrene-butadiene rubber or polybutadiene as the core and poly(methyl methacrylate) as the shell;
wherein the vinyl-containing benzoxazine resin comprises a prepolymer of polybutadiene and benzoxazine resin, an allyl-containing bisphenol A benzoxazine resin, an allyl-containing bisphenol F benzoxazine resin, an allyl-containing dicyclopentadiene benzoxazine resin, an allyl-containing oxydianiline benzoxazine resin or a combination thereof; and
wherein the maleimide resin comprises polyphenylmethane maleimide, bisphenol A diphenyl ether bismaleimide, 3,3′-dimethyl-5,5′-diethyl-4,4′-diphenylmethane bismaleimide, 3,3′-dimethyl-5,5′-dipropyl-4,4′-diphenylmethane bismaleimide, maleimide resin containing aliphatic long chain structure or a combination thereof.
