A kind of thermosetting resin composition, with the thermosetting polyphenylene ether resin Jing Guo graft modification for main resin, the molecular backbone end and molecular side chain position of the thermosetting polyphenylene ether resin, with unsaturated functional group, and its number-average molecular weight (Mn) is 2, 000 to 25, when 000, its functional group's quantity can be controlled by appropriate OH valences, it is suitable for and butadiene resin, inorganic particle, fire retardant, crosslinking agent and hardening initiator are deployed into thermosetting resin composition jointly, after hardened, the advantages of modified polyphenylene ether resin can be showed, has low-k, low-dielectric loss, the features such as high Tg ﹑ high rigidities and most excellent cutting property of prepreg. |
