Polysulfide polymers as an important class of polymers are used in different applications as sealants, adhesives, etc. They are usually synthesized by reaction of disodium polysulfides with dihalo compounds to yield liquid or solid polymers. Their most important advantages are excellent adhesion to different surfaces, creation of no defect in sealant under stress and pressure, resistance against to fuels and solvents, very low gas and steam permeability, and high resistance to ozone and UV. This article aims to review methods of synthesis, properties, and applications of polysulfide polymers. Also, polysulfide-based nanocomposites and blends are also briefly discussed.

多硫化物聚合物：合成，共混，纳米复合材料及其应用

作为重要的一类聚合物，多硫化物聚合物在不同的应用中用作密封剂，粘合剂等。它们通常是通过多硫化二钠与二卤代化合物反应生成液体或固体聚合物而合成的。它们最重要的优点是在不同表面上具有出色的附着力，在压力和压力下不会在密封胶中产生缺陷，对燃料和溶剂的抵抗力，极低的气体和蒸汽渗透性以及对臭氧和紫外线的高度抵抗力。本文旨在综述聚硫化物聚合物的合成方法，性质和应用。此外，还简要讨论了基于多硫化物的纳米复合材料和共混物。
