Aqueous suspension of polyisobutylene (PIB) was stabilized via application of anionic surfactant of sodium lauryl sulfate (SLS) and co-surfactants of stearyl and cetyl alcohols. Suspensions were produced via the so-called direct emulsification technique. Some characterization tests including zeta potential, particle size, turbidity, conductivity, and rheology measurements were demonstrated to analyze the stability of produced suspensions. Turbidity and particle size measurements showed that just some of the samples were stable while the others exhibited partial aggregation of particles. The characterization tests showed that the sample contained 2 g of polyisobutylene, 0.45 g SLS, 0.175 g stearyl, and 0.263 g cetyl alcohols, i.e., co-surfactant ratio of 0.66, in 80 mL of water exhibited appropriate stability. Possession of high zeta potential of − 93.65 mV, conductivity of 570 mS/cm, an average particle size of 10 μm, and good rheological behavior besides the stable appearance revealed that this sample did not undergo agglomeration, flocculation, or any phase separation.

聚异丁烯水悬浮液的制备、稳定和表征

聚异丁烯 (PIB) 的水悬浮液通过应用十二烷基硫酸钠 (SLS) 的阴离子表面活性剂和硬脂醇和鲸蜡醇的辅助表面活性剂来稳定。悬浮液是通过所谓的直接乳化技术生产的。一些表征测试，包括 zeta 电位、粒度、浊度、电导率和流变学测量，被证明可以分析产生的悬浮液的稳定性。浊度和粒度测量表明，只有一些样品是稳定的，而其他样品则表现出部分颗粒聚集。表征测试表明，样品在 80 mL 水中含有 2 g 聚异丁烯、0.45 g SLS、0.175 g 硬脂醇和 0.263 g 鲸蜡醇，即助表面活性剂比例为 0.66，表现出适当的稳定性。具有 - 93.65 mV 的高 zeta 电位、570 mS/cm 的电导率、10 μm 的平均粒径和良好的流变行为以及稳定的外观表明该样品没有发生团聚、絮凝或任何相分离。图形摘要图形摘要
