摘要：

Polyphenylene oxide (PPO) with low dielectric constant (εr) and dielectric loss factor (tanδ) was an ideal material for manufacturing high frequency copper clad laminates, but its industrial application in the field of copper clad laminates was limited due to its lack of crosslinkable active groups. In this paper, brominated polyphenylene ether (BrPPO) with the bromination rate of 15% was prepared through bromination reaction of PPO with N-bromosuccinimide (NBS). Maleimide was protected by furan through Diels-Alder (DA) reaction and reacted with BrPPO. The modified polyphenylene ether (MPPO) with maleimide side groups was successfully synthesized, giving PPO crosslinkable active sites. The structure and properties of MPPO were characterized by 1H-NMR, FT-IR, differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). DSC and TGA analyses show that the furan protection groups can be removed at 164 ℃ and MPPO crosslinks at around 320℃. The TGA results imply that the maleimide group content of MPPO is about 11.4%. The dielectric properties, heat resistance and dimensional stability of copper clad laminate prepared by MPPO are improved. © 2022, Editorial Board of Polymer Materials Science & Engineering.
