We describe six aqueous formulations prepared from anionic HYPAN, an acrylic acid/acrylamide copolymer, and cationic poly(diallyldimethylammonium chloride) (PDADMAC) for stabilization of loamy sandy soil and quartz sand. The formulations were deposited on the surface of soil and sand that after drying resulted in the formation of protective polymer–soil and polymer–sand coatings. Most formulations gave mechanically stable coatings with a strength of 100–200 kg cm⁻² and sustained a storm wind of 76 km h⁻¹. A non-stoichiometric HYPAN–PDADMAC polycomplex with a 10-fold excess of anionic HYPAN units formed the water resistant coatings, which retained 99% soil and 90% sand. These characteristics were superior to those for coatings made from a conventional binder polyacrylamide. Additionally, the coating from soil and ‘anionic’ non-stoichiometric interpolyelectrolyte complex increased the total amount of stored water and lengthened the time of water release. Anionic polymer formulations did not exhibit antimicrobial action against bacteria and yeast in both solutions and films. Cationic polymer formulations manifested strong antimicrobial action against bacteria and yeast in solutions, and suppressed the growth of Gram-positive bacteria and yeast in films. Taking into account the commercial availability of the initial polymers and a simple procedure for polycomplex preparation, there is great potential for anionic polymer formulations as anti-erosion binders and soil conditioners. © 2021 Society of Industrial Chemistry.

基于水解聚丙烯腈的聚电解质间复合物用于土壤和地面的抗侵蚀稳定

我们描述了由阴离子 HYPAN、丙烯酸/丙烯酰胺共聚物和阳离子聚 (二烯丙基二甲基氯化铵) (PDADMAC) 制备的六种水性配方，用于稳定壤质沙土和石英砂。配方沉积在土壤和沙子表面，干燥后形成保护性聚合物-土壤和聚合物-沙子涂层。大多数配方提供机械稳定的涂层，强度为 100–200 kg cm ^{-2并承受 76 km h -1}的暴风. 具有 10 倍过量阴离子 HYPAN 单元的非化学计量 HYPAN-PDADMAC 复合物形成了防水涂层，该涂层保留了 99% 的土壤和 90% 的沙子。这些特性优于由传统粘合剂聚丙烯酰胺制成的涂料。此外，土壤涂层和“阴离子”非化学计量的聚电解质间复合物增加了储存水的总量并延长了水的释放时间。阴离子聚合物配方在溶液和薄膜中均未表现出对细菌和酵母菌的抗菌作用。阳离子聚合物制剂对溶液中的细菌和酵母菌表现出很强的抗菌作用，并抑制了革兰氏阳性细菌和酵母菌在薄膜中的生长。考虑到初始聚合物的商业可用性和用于制备多络合物的简单程序，阴离子聚合物制剂作为抗侵蚀粘合剂和土壤改良剂具有巨大潜力。© 2021 工业化学学会。
