The current study presents an attempt to develop two molecules, namely sulfonated aromatic diol (SAD) and sulfonated aromatic diamine (SADAM), to induce flame retardancy, thermal stability, and dispersion ability for water-based polyurethane dispersions (WPUDs). The previously reported itaconic acid-based polyester polyol was used for prepolymer synthesis as well as for chain extension. Pre- and post-sulfonated compounds were subjected to characterization tests such as FTIR, ¹³C-NMR, ¹H-NMR, and CHNS for confirmation of their structures. The standard dispersant used for the basis of comparison was commercially available dimethyl propionic acid (DMPA). WPUDs were synthesized in different molar concentrations of DMPA, SAD, and SADAM, and the covalent incorporation of all three molecules in the polymer backbone was confirmed by FTIR. The WPUD films were subjected to various thermal tests like TGA and DSC as well as mechanical tests like flexibility and pencil hardness. WPUD films obtained from SADAM showed a remarkable increase in Tg as well as char content. The THRI values for SAD- and SADAM-based films were better than DMPA-based films. SAD- and SADAM-based WPUD films also showed an increase in LOI value and UL-94 ratings with the maximum LOI value of 26. Dispersions based on DMPA showed better stability as compared to dispersions based on SAD and SADAM.

当前的研究提出了开发两个分子的尝试，即磺化芳族二醇（SAD）和磺化芳族二胺（SADAM），以诱导阻燃性，热稳定性和水基聚氨酯分散体（WPUDs）的分散能力。先前报道的衣康酸基聚酯多元醇用于预聚物合成以及扩链。对磺化前后的化合物进行了表征测试，例如FTIR，¹³ C-NMR，¹H-NMR和CHNS用于确认其结构。用于比较的标准分散剂是可商购的二甲基丙酸（DMPA）。在不同摩尔浓度的DMPA，SAD和SADAM中合成了WPUD，并且通过FTIR证实了这三个分子在聚合物主链中的共价结合。WPUD膜经受了各种热测试（例如TGA和DSC）以及机械测试（例如柔韧性和铅笔硬度）。从SADAM获得的WPUD膜显示出Tg和炭含量显着增加。基于SAD和SADAM的薄膜的THRI值优于基于DMPA的薄膜。基于SAD和SADAM的WPUD膜还显示出LOI值和UL-94等级的提高，最大LOI值为26。
