Abstract

See full text

The present invention relates to a halogen-free resin composition, a prepreg and a laminate prepared therefrom. The halogen-free resin composition comprises, based on the weight parts of organic solids, (A) from 40 to 80 parts by weight of allyl-modified benzoxazine resin, (B) from 10 to 20 parts by weight of hydrocarbon resin, (C) from 10 to 40 parts by weight of allyl-modified polyphenyl ether resin, (D) from 10 to 20 parts by weight of allyl-modified bismaleimide resin, (E) from 0.01 to 3 parts by weight of an initiator, (F) from 10 to 100 parts by weight of a filler, and (G) from 0 to 80 parts by weight of a phosphorus-containing flame retardant. The prepreg and laminate prepared from the halogen-free resin composition have lower dielectric constant and dielectric loss tangent value, higher peel strength, high glass transition temperature, excellent thermal resistance and better flame retardant effect.
