Polyhydroxyurethanes(PHUs)have received considerable attention in the last decade as potential alternatives to traditional phosgene-based polyurethanes(PUs).The development of suitable 5cc(five membered-ring cyclic carbonate)precursors bearing multiple carbonate moieties(multi-5ccs)is a key requisite for preparing PHUs by polyaddition reaction with bis-or *** sustainable PHUs from cO_(2)-based five-membered cyclic carbonates(5ccs)obtained from biobased epoxides is a valuable strategy to bridge cO_(2) utilization and the upcycling of renewable *** this context,while many multi-5cc monomers reported in the literature are oil-based,recent efforts have led to the development of a large variety of multifunctional 5ccs that are produced by the combination of cO_(2) and renewable resources such as fatty acids and vegetable oils,lignin,terpenes,and *** this work,recent crucial advances(2019—2023)on PHUs prepared from bis-and multi-5ccs produced from cO_(2) and(partially/potentially)biobased substrates are reviewed with respect to their synthesis,thermal and mechanical properties,and their recent,emerging applications.

To the Editor : Barcelona clinic Liver cancer(BcLc) Stage c hepatocellular carcinoma(Hcc) with vascular invasion has been considered unresectable. However, the curative rate from systemic treatment is rather dismal. Even with the use of immunotherapy, complete remission is less than 10% [ 1 ]. On the contrary, recent advances in transplant oncology, especially in the application of liver transplant-related surgical techniques in complex liver resections, make the operation possible for patients with locally advanced Hcc who were previously considered to be unresectable [ 2 ]. We hereby present the surgical management of a patient with giant Hcc in right liver lobe with inferior vena cava(IVc) invasion.
