    • Disclosed herein are compositions and methods of making polythiourea and polythiourethane foams and coatings. In one embodiment, a method of preparing a polythiourea composition involves combining at least one polyamine compound, at least one polyisothiocyanate compound, and at least one catalyst to form a reaction mixture, and mixing the reaction mixture to form the polythiourea composition. In some embodiments, the polyamine compound may have an amine functionality of two or more, and is present in an amount of about 14 wt % to about 40 wt % of the reaction mixture. In some embodiments, the polyisothiocyanate compound may have a functionality of two or more, and is present in an amount of about 60 wt % to about 86 wt % of the reaction mixture. In some embodiments, the catalyst may be present in an amount of about 0 wt % to about 5 wt % of the reaction mixture.
    • 本文公开了制备聚硫脲和聚硫氨酯泡沫和涂料的组合物和方法。 在一个实施方案中,制备聚硫脲组合物的方法包括将至少一种多胺化合物,至少一种多异硫氰酸酯化合物和至少一种催化剂混合以形成反应混合物,并将该反应混合物混合以形成聚硫脲组合物。 在一些实施方案中,多胺化合物可以具有两个或更多个胺官能度,并且以反应混合物的约14重量%至约40重量%的量存在。 在一些实施方案中,多异硫氰酸酯化合物可以具有两个或更多个的官能度,并且以反应混合物的约60重量%至约86重量%的量存在。 在一些实施方案中,催化剂可以以反应混合物的约0重量%至约5重量%的量存在。
