摘要： A prepreg and uses thereof are provided. The prepreg includes an organic fiber woven fabric impregnated or coated with a thermally curable resin composition, wherein the thermally curable resin composition includes:



(A) a polyphenylene ether resin having an unsaturated functional group;
(B) a polyfunctional vinyl aromatic copolymer; and
(C) a compound having the structure of formula (I),










wherein, in formula (I), X is a C1-C10 linear or branched alkylene; and
the polyfunctional vinyl aromatic copolymer is prepared by copolymerizing one or more divinyl aromatic compounds with one or more monovinyl aromatic compounds.

摘要： A dielectric composite is provided. The dielectric composite includes:at least one first dielectric layer; and at least one second dielectric layer, wherein the first dielectric layer has a thermal coefficient of dielectric constant (TCDk) not higher than −150 ppm/° C., and the second dielectric layer has a TCDK not lower than 50 ppm/° C.; and the dielectric composite has a dielectric constant (Dk) not lower than 4, and a TCDk ranging from 0 to −150 ppm/° C.
