Abstract

Interpolyelectrolyte complexes of a linear cationic polymer poly(diallyldimethylammonium chloride) and anionic microgel particles with carboxyl groups in a pH 6 buffer solution are presented. Dispersions of the microgel and its complexes—negatively charged with a 3-fold molar excess of the anionic groups of the microgel and positively charged with a 3-fold molar excess of the cationic groups of the polycation—retain aggregative stability for six months. When applying 1 wt % dispersions of the microgel and complex on the surface of the soil with a high sand content, polymer-soil coatings with a mechanical strength of 19 to 61 kg/m² depending on the composition of the dispersion are formed. These indicators significantly exceed those for coatings obtained by applying a 1 wt % solution of a linear anionic polymer, poly(acrylic acid), on the soil surface. Coatings involving microgel and its complexes remain stable at an air flow rate of 190 km/h.

稳定沙土抗风蚀的聚电解质凝胶

摘要

提出了一种线性阳离子聚合物聚（二烯丙基二甲基氯化铵）与在pH 6的缓冲溶液中带有羧基的阴离子微凝胶颗粒的聚电解质复合物。微凝胶及其络合物的分散体（带负电荷的3倍摩尔过量的微凝胶的阴离子基团带正电荷，带正电荷的3倍摩尔过量的聚阳离子的阳离子基团）保持了六个月的聚集稳定性。在含沙量高的土壤表面上施加1 wt％的微凝胶和复合物分散液时，机械强度为19至61 kg / m ^2的聚合物-土壤涂料取决于分散体的组成而形成。这些指示剂大大超过了通过在土壤表面上施加1 wt％的线性阴离子聚合物（聚丙烯酸）溶液获得的涂料的指示剂。涉及微凝胶及其配合物的涂料在空气流速为190 km / h时保持稳定。
