This limonene-derived polymer has the highest glass transition temperature ever reported for a polycarbonate. Having a high glass transition temperature has other implications – the new plastics require higher temperatures to melt, which make them safer for everyday use. Moreover, this new polymer can also offer a myriad of new applications for polycarbonates and block copolymers using appropriate material formulations.
