✦ Synopsis

The enzyme-catalyzed synthesis of poly(p-ethylphenol) (PEP) has received considerable interest in recent years. Nevertheless, the limited molecular weights restricts its application. In our preliminary research, PEP was modified by copolymerization with polycarbonates through both transesterification at high temperature, and triphosgene at low temperature to form polycarbonate-co-poly(p-ethylphenol) (PC-co-PEP). FTIR, NMR, GPC, and thermal analysis verified the formation of PC-co-PEP. The copolymers have an optical absorption in the UV range.
