Abstract

Three polymerizable spans based on sorbitan monoesters were synthesized and copolymerized with the acrylamide at different ratios to prepare nine amphiphilic copolymers via the inverse emulsion copolymerization technique. The FTIR, ¹H-NMR, and viscosity average molecular weight ways characterized the synthesized monomers and copolymers. The general designation for the copolymers is PSnSs. Surface active and thickening properties for the aqueous solutions of the prepared copolymers were investigated. The influence of salts' concentration and temperature variation on the apparent viscosity and surface/interfacial activity was studied for the selected copolymers, and their emulsification ability was also examined. The results showed that the attached polymerizable spans enhanced the properties and capabilities of the acrylamide copolymers. This enhancement increased with increasing the attached monomers' ratio and lipophilic chain length. The copolymer PS60S-3 displayed the best values and capabilities with values at 0.2 wt% in distilled water for the γ_ST, γ_IFT, and η_app equal 42.25 mN.m⁻¹, 13.3 mN.m⁻¹, and 495.76 mPa.s, respectively. It has the potential to be used as a bi-functional flooding agent.

基于可聚合跨度的双功能两亲性丙烯酰胺共聚物的合成

以山梨醇单酯为基料，合成了3种可聚合膜，并以不同比例与丙烯酰胺共聚，通过乳液反聚合技术制备了9种两亲性共聚物。用FTIR、1H-NMR和粘度平均分子量等方法对合成的单体和共聚物进行了表征。共聚物的一般名称是PSnSs。研究了所制备共聚物水溶液的表面活性和增稠性能。研究了盐浓度和温度变化对所选共聚物表观粘度和表面/界面活性的影响，并考察了它们的乳化能力。结果表明，附着的可聚合跨度提高了丙烯酰胺共聚物的性能和性能。这种增强作用随着附着单体比例和亲脂链长度的增加而增强。共聚物PS60S-3在蒸馏水中对γST， γIFT和ηapp = 42.25 mN的值为0.2 wt%时表现出最佳值和性能。m−1,13.3 mN。m−1,495.76 mPa。年代,分别。它具有作为双功能驱油剂的潜力。

期刊介绍： "Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad. "Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
