Inverse vulcanization of cheap elemental sulfur (S) to prepare polymers that simultaneously possess high sulfur content and good solubility is still in its infancy. In this paper, the authors report the synthesis of a novel S-rosin (Ro) copolymer (Sx-Ro) based on the inverse vulcanization of S with natural Ro. The sulfur content of Sx-Ro can be regulated in a wide range, while Sx-Ro still presents excellent solubility in low boiling point solvents at high sulfur content. Even if the sulfur content in Sx-Ro is as high as 50%, its solubility in tetrahydrofuran (THF) can still reach 26 mg mL−1. Moreover, the Sx-Ro exhibits excellent ultraviolet (UV) absorption capability in the entire UV region (200–400 nm) and can be utilized as an effective anti-UV agent to enhance the UV-blocking performance of other polymers (e.g., polymethyl methacrylate [PMMA] and polystyrene [PS]) without compromise of transparency and thermal stability. Considering the fine solubility and superior UV-blocking properties of Sx-Ro, this work not only provides a versatile and effective anti-UV material but also opens new opportunities for value-added utilization of abundant S and Ro resources.

元素硫与天然松香反硫化制备具有优异溶解性和紫外线阻隔性能的高硫含量聚合物
廉价元素硫(S)的逆硫化制备同时具有高硫含量和良好溶解性的聚合物仍处于起步阶段。在本文中,作者报告了基于 S 与天然 Ro 的反硫化合成一种新型 S-松香 (Ro) 共聚物 (S x -Ro)。S x -Ro的硫含量可以在很宽的范围内调节,而 S x -Ro 在高硫含量的低沸点溶剂中仍然表现出优异的溶解性。即使S x -Ro 中的硫含量高达50%,其在四氢呋喃(THF)中的溶解度仍可达到26 mg mL -1。此外,S x-Ro 在整个 UV 区域(200–400 nm)表现出优异的紫外线 (UV) 吸收能力,可用作有效的抗紫外线剂,以增强其他聚合物(例如聚甲基丙烯酸甲酯 [PMMA])的紫外线阻隔性能和聚苯乙烯 [PS]),而不会影响透明度和热稳定性。考虑到 S x -Ro良好的溶解性和优异的紫外线阻隔性能,该工作不仅提供了一种通用且有效的抗紫外线材料,而且为丰富的 S 和 Ro 资源的增值利用开辟了新的机会。
