摘要

摘要评估了基团长度不同的阳离子表面活性剂的凝结力。测试了癸基氯化吡啶、十二烷基氯化吡啶、十六烷基溴化吡啶、十六烷基三甲基溴化铵和烷基苄基二甲基氯化铵。混凝剂的消耗量与商用阳离子聚电解质聚二烯丙基二甲基氯化铵的消耗量相当。提出了表面活性剂对胶乳体系聚合稳定性的干扰作用的假设。提出了基于胶束-球相互作用的表面活性剂肌动蛋白机制。

Behavior of Cationic Surfactants in Rubber Latex Coagulation

The coagulating power of cationic surfactants differing in the length of the radicals was evaluated. Decylpyridinium chloride, dodecylpyridinium chloride, cetylpyridinium bromide, cetyltrimethylammonium bromide, and alkylbenzyldimethylammonium chloride were tested. The coagulant consumption corresponds to the consumption of the commercially used cationic polyelectrolyte, polydiallyldimethylammonium chloride. A hypothesis concerning the disturbing effect of surfactants on the aggregative stability of latex systems was put forward. The surfactant actin mechanism based on micellar-globular interaction was suggested.

期刊介绍： Russian Journal of Applied Chemistry (Zhurnal prikladnoi khimii) was founded in 1928. It covers all application problems of modern chemistry, including the structure of inorganic and organic compounds, kinetics and mechanisms of chemical reactions, problems of chemical processes and apparatus, borderline problems of chemistry, and applied research.
