A versatile strategy involves anionic ring-opening polymerization (AROP) and thiol-ene reaction was contributed for the construction of hyperbranched ionic surfactants. A series of hyperbranched surfactants composed of polyether skeleton and various ionic side groups such as anion, cation and zwitterion were synthesized and labeled as HPE_anionic, HPE_cationic and HPE_zwitterionic, respectively. The chemical structures of all the intermediate and final products were verified by means of fourier transform infrared (FTIR) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy. The surface and interfacial tension reduction performances of three obtained ionic surfactants were systematically investigated. And the results confirmed all the resultant surfactants could effectively reduce the surface and interfacial tension of the solution, and the CMC values were all determined approximately to 0.1 mg/mL. Meanwhile, three surfactants exhibit relatively low Krafft temperatures (below 6 ℃) and good wettability to oil-wetted surface. To further explore their promising applications, HPE_anionic was proposed for use as a stabilizer in emulsion polymerization. Dynamic light scattering (DLS) measurements as well as transmission electron microscope (TEM) observation confirmed well-defined latex was obtained indeed. Moreover, as compared to latex synthesized by using the traditional small molecule compound surfactants, latex synthesized using HPE_anionic as stabilizer exhibit improved tolerance to salinity. This beneficial result is probably caused by the special hyperbranched structure of HPE_anionic, which contributes both electrostatic repulsion and steric hindrance drive force for the stabilization of latex particles.

一种通用的策略涉及阴离子开环聚合 (AROP)，硫醇-烯反应有助于构建超支化离子表面活性剂。合成了一系列由聚醚骨架和阴离子、阳离子、两性离子等离子侧基组成的超支化表面活性剂，并标记为HPE_阴离子型、HPE_阳离子型和HPE_{两性离子型。}， 分别。通过傅里叶变换红外 (FTIR) 光谱和核磁共振 (NMR) 光谱验证了所有中间产物和最终产物的化学结构。系统地研究了三种获得的离子表面活性剂的表面和界面张力降低性能。结果证实，所得表面活性剂均能有效降低溶液的表面张力和界面张力，CMC值均约为0.1 mg/mL。同时，三种表面活性剂均表现出较低的克拉夫特温度（低于6 ℃）和对油湿表面的良好润湿性。为了进一步探索其有前景的应用，HPE_阴离子建议用作乳液聚合中的稳定剂。动态光散射 (DLS) 测量以及透射电子显微镜 (TEM) 观察证实确实获得了定义明确的胶乳。此外，与使用传统小分子复合表面活性剂合成的胶乳相比，使用HPE_阴离子作为稳定剂合成的胶乳对盐度的耐受性有所提高。这种有益的结果可能是由 HPE_阴离子的特殊超支化结构引起的，它有助于静电排斥和空间位阻驱动力，以稳定乳胶颗粒。
