Research output: Patent


The present disclosure describes, in part, a polymer, for example a thermoplastic polyurethane elastomer, comprising one or more subunits comprising (i) at least one dianhydrohexitole moiety (ii) at least one urethane moiety and (ill) a thiol moiety having two or more sulphur atoms. The thermoplastic polyurethane elastomers may be biodegradable and possess excellent thermoplastic properties, including outstanding toughness, resulting from its semi-crystallinity and low glass transition temperature, that surpasses many leading plastics such as nylon 6 and high-density polyethylene (HOPE) and methods of making same.
