Triptycenediol-2,5 polycarbonates

The synthesis and properties of polycarbonate and copolycarbonates of trypticenediol-2,5 are considered. The mechanical properties of mixtures of industrial polycarbonate and polycarbonate of trypticenediol-2,5 are investigated. It is established that polycarbonate and copolycarbonates of trypticenediol-2,5 have higher glass transition temperatures and improved chemical resistance compared to polycarbonate of 2,2-di-(4-oxyphenyl)-propane. It has also been shown that the presence of trypticene units improves the mechanical properties of the mixtures compared to industrial polycarbonate
