Synthesis and Characterization of Partially Biobased Aromatic (Co)polycarbonates Containing Biphenylene Units and Pendant Pentadecyl Chains

Abstract: 1,1"-biphenyl]-4,4"-diol (PBD) is synthesized starting from cashew nut shell liquid-a by-product of cashew processing industry. A new series of partially biobased aromatic (co)polycarbonates possessing biphenylene units and pendant pentadecyl chains is synthesized by solution polycondensation of PBD or varying compositions of PBD and bisphenol-A with triphosgene in dry dichloromethane. Inherent viscosities and number average molecular weights of (co)polycarbonates are in the range 0.51-1.24 dL g −1 and 18 × 10… Show more

“…Similar observations on deviation in T g values from Fox equation have been reported by us previously for poly(ether sulfone) s 54 and aromatic polycarbonates. 26,55 Further experimental and computational studies would be valuable for better understanding of the effect of composition and sequence distribution on T g values of copolyesters possessing pendant maleimide groups.…”

“…Polycarbonate (PC) is a high‐performance thermoplastic engineering polymer with excellent transparency, impact strength, thermal resistance, 1,2 low water uptake 3,4 and high dimensional stability 5,6 . It has a wide range of applications in our daily life: engineering building materials, electronic materials, medical devices and optical materials, and personal products like drinking bottles 7,8 . At present, commercial polycarbonates are prepared via interfacial polycondensation or the melt transesterification process 9 .…”

“…The glass transition temperature of bisphenol‐A polycarbonate is 140–150°C, which has excellent performance advantages in various application environments 11 . However, with the continuous development of high‐frequency communication technology, BPA‐PC with a dielectric constant of 3.0 is limited in its application in the field of high‐frequency communication 8,12 . To further widen polycarbonate application areas, it is desirable to synthesize new low‐dielectric aromatic polycarbonates based on other bisphenol 13,14 .…”
