Glycerol propoxylate based oil loving sorbents were prepared through bulk polymerization, without using of an activator, initiator, or catalyst. Fourier transform infrared spectroscopy (FTIR), C and Si CPMAS nuclear magnetic resonance (NMR), as well as elemental analysis and thermal gravimetric analysis (TGA) were operated in order to identify the structural and thermal features of sorbents. The synthesized gels were employed as absorbents for various organic solvents and oils. The swelling capacity, absorption-desorption kinetics, reusability, and selective removal from an oil/water mixture were also examined. To explore the effects of a crosslinker's concentration on oil absorption capacity, star type propoxylate monomers were reacted at different concentration of tris[3-(trimethoxysilyl)propyl]isocyanurate (ICS) crosslinker; swelling capacity was calculated using dichloromethane as an organic solvent. Oil removal ability from the water surface is another important section contained within this article.
基于丙氧基化甘油的亲油吸附剂通过本体聚合制备，无需使用活化剂、引发剂或催化剂。采用傅里叶变换红外光谱（FTIR）、C和Si CPMAS核磁共振（NMR）以及元素分析和热重分析（TGA）来确定吸附剂的结构和热特性。合成的凝胶用作各种有机溶剂和油的吸附剂。还研究了溶胀能力、吸附-解吸动力学、可重复使用性以及从油/水混合物中的选择性去除。为了探究交联剂浓度对吸油能力的影响，星形丙氧基化单体在不同浓度的三[3-（三甲氧基甲硅烷基）丙基]异氰脲酸酯（ICS）交联剂下反应；使用二氯甲烷作为有机溶剂计算溶胀能力。从水面去除油的能力是本文包含的另一个重要部分。
