Myo-inositol, a naturally occurring cyclic compound obtained from rice bran, was transformed into a divinyl derivative bearing a rigid hexaoxadiamantane (HODAM) core composed of two orthoester moieties. The divinyl compound underwent radical polyaddition with dithiols to afford the corresponding semi-crystalline polythioethers, the melting temperatures (T_m) of which were above 240 °C. Furthermore, the divinyl compound was transformed into a HODAM-bearing diol via the radical addition of 2-mercaptoethanol to the vinyl groups. The diol product was used as a rigid monomer in polyurethane synthesis. The obtained polyurethanes exhibited glass transition temperatures (T_g) ranging from 55 to 110 °C.

肌肌醇，从米糠中获得的天然存在的环化合物，转化成二乙烯基衍生物带有两个原酸酯基团所组成的刚性hexaoxadiamantane（HODAM）核心。所述二乙烯基化合物接受了根治性加聚用的二硫醇，得到相应的半结晶聚硫醚，熔融温度（Ť_米）是其中的高于240℃。此外，二乙烯基化合物通过 2-巯基乙醇与乙烯基的自由基加成转化为带有 HODAM 的二醇。二醇产品用作聚氨酯合成中的刚性单体。所得聚氨酯的玻璃化转变温度 ( T _g ) 范围为 55 至 110 °C。
