POLYTHIOUREA COMPOSITIONS AND METHODS OF USE |
| 摘要 |
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. |
