摘要：A rosin-based monomer with thermally crosslinkable benzocyclobutene groups was synthesized in this study. The structure of the monomer was examined using mass spectroscopy, Fourier transform infrared spectroscopy, and nuclear magnetic resonance spectroscopy. An amorphous crosslinked network with dielectric constant of 2.71 and dielectric loss of 0.0012 at 30 MHz was formed when the monomer was polymerized at high temperature (> 200 degrees C). The polymer film exhibits surface roughness (Ra) of 0.337 nm in a 5.0 x 5.0 mu m(2) area and the water contact angle of 110 degrees. In addition, results from thermogravimetric analysis indicate that the polymer has T-5% = 402 degrees C, and differential scanning calorimetry measurements show that the glass transition temperature is at least 350 degrees C. Results from nanoindentation tests show that the hardness and Young's modulus of the polymer are 0.418 and 4.728 GPa, respectively. These data suggest that this new polymer may have potential applications in electronics and microelectronics. (c) 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 137, 48831.
