    Abstract: A resin composition includes a prepolymer which is prepared from a mixture subjected to a prepolymerization reaction, the mixture including 100 parts by weight of a first maleimide resin, 40 to 60 parts by weight of a siloxane compound and 10 to 30 parts by weight of a diamine compound, wherein: the first maleimide resin includes bisphenol A diphenyl ether bismaleimide; the siloxane compound includes a compound of Formula (I), having a molecular weight of 2200 to 2600 g/mol; and the diamine compound includes 4-aminophenyl-4-aminobenzoate. The resin composition may be used to make various articles, such as a varnish, a prepreg, a resin film, a laminate or a printed circuit board, and at least one of the following properties can be improved, including resin compatibility and X-axis coefficient of thermal expansion.

    Abstract: The invention discloses a method for manufacturing a new sound-absorbing and noise-reducing material by using polyimide foam scraps, cutting and processing the scraps generated in the process of polyimide foam production into particles of different sizes, drying red iron oxide or black iron oxide or titanium dioxide as inorganic additive, and then using each component in parts by weight, putting the inorganic additive into the mixer, and then putting the polyimide foam particles of different sizes into the mixer to mix, injecting the curing agent into the mixer to continue mixing, and finally adding the catalyst into the mixer to continue mixing, putting the mixed material into the mold evenly to form the film, leaving it for 10 hours, opening the mold, taking out the product, removing the burrs, and cutting the product according to customer needs, and packing it in a carton for storage.
