Thionocarbonate (–O–CS–O–) and xanthate (–S–CS–O–) cyclic monomers were synthesised by cyclothiocarbonation of 2-deoxy-D-ribose- and D-xylose-derived diols with carbon disulfide, then polymerised using organocatalytic ring-opening methods. Regular polymer linkages were obtained, with the sugar backbone influencing the regioselectivity of monomer opening. Thermal analysis revealed lower glass transition temperatures compared to carbonate analogues and a low onset of thermal degradation.

由糖聚合物和CS ₂：由2-脱氧-衍生的含硫单体的合成和开环聚合d -核糖和d -木糖†

硫代碳酸酯（–O–CS–O–）和黄原酸酯（–S–CS–O–）环状单体是通过将2-脱氧-D-核糖和D-木糖衍生的二醇与二硫化碳进行环硫代碳酸合成的，然后使用有机催化开环方法。获得规则的聚合物键，其中糖主链影响单体开口的区域选择性。热分析表明，与碳酸盐类似物相比，玻璃化转变温度更低，并且热降解的发生率低。
