Title:
ALLYL-TYPE FLAME-RETARDANT PREPOLYMER, RESIN COMPOSITION, COMPOSITE RESIN, PREPREG AND LAMINATED BOARD
Document Type and Number:
WIPO Patent Application WO/2023/125802
Kind Code:
A1
Abstract:
Disclosed in the present invention are an allyl-type flame-retardant prepolymer, a resin composition, a composite resin, a prepreg and a laminated board. The allyl-type flame-retardant prepolymer provided by the present invention is prepared by prepolymerizing an allyl-type benzoxazine compound and an allyl-type phosphorus-containing compound, which have a ratio of 100:(20-80) in parts by mass. The resin composition, the composite resin, the prepreg and the laminated board prepared from the allyl-type flame-retardant prepolymer provided by the present invention are high in flame-retardant properties, excellent in high-temperature modulus properties, good in heat resistance and water absorption rate and excellent in dielectric properties.
