Document Type and Number:
WIPO Patent Application WO/2018/103199
Kind Code:
A1
Abstract:
Provided in the present invention is a thermosetting resin composition, comprising phosphorus-containing active ester and epoxy resin, the phosphorus-containing active ester being copolymerised using bis-aromatic formyl chloride hydrocarbyl phosphine oxide and one of bis-hydroxyl aromatic hydrocarbyl phosphine oxide, bis-hydroxyl aromatic oxyhydrocarbyl phosphine oxide, or hydroxylated DOPO, and then obtained from aromatic formyl chloride end capping; the thermosetting resin composition provided in the present invention has the advantages of good thermal stability, humidity resistance and heat resistance, a low dielectric constant and dielectric loss tangent, a low rate of water absorption, and halogen-free flame-retardant properties, and has excellent machinability; also provided in the present invention are applications of the thermosetting resin composition for resin sheet material, resin composite metal foil, prepreg, laminated plate, metal foil-clad laminated plate, and printed circuit boards.
