  • Patent number: 10519352
    Abstract: An adhesive composition with high frequency characteristics and the application thereof; wherein, the adhesive composition has a total weight of (A), (B) and (C) in 100 parts by weight, comprising: (A) 40-80 parts by weight of solvent-soluble polyimide; (B) 5-30 parts by weight of propenyl-modified polyphenylene oxide resin; (C) 10-30 parts by weight of epoxy resin; and optionally comprising at least one of the following components: (D) flexibilizer; (E) flame retardant; (F) inorganic filler; (G) coupling agent; and (H) catalyst. The adhesive composition has the advantages of low dielectric constant, low dielectric loss, favorable heat resistance and low-temperature (<180° C.) adhesion. The adhesive composition can be used for preparing high-frequency protective membrane and high-frequency adhesive film.
