Abstract: The present disclosure relates to a modified bismaleimide prepolymer, a preparation method thereof, and use thereof. The modified bismaleimide prepolymer is prepared from raw materials comprising a bismaleimide resin and a modifier. The modifier is a 4,4?-bis(allyl-benzoic acid) biphenyl ester-based allyl compound, or a combination of the 4,4?-bis(allyl-benzoic acid) biphenyl ester-based allyl compound and another type of bismaleimide resin modifier.

Abstract: The present invention relates to modified carbon black and a production method therefor, a resin composition and copper clad laminate. The modified carbon black comprises carbon black and a modified group; the surface of the carbon black has an acyl chloride group; the modified group is formed by a modified macromolecule and the acyl chloride group undergoing a grafting reaction; and the modified macromolecule is an alcohol macromolecule.

Abstract: The present disclosure provides a modified allyl compound, and a modified bismaleimide prepolymer. The modified allyl compound is represented by formula (1), has a cyclopentadiene structure represented by formula (2), and contains a benzene ring or a benzene ring substituted with a linear alkane of lower polarity.
