Ushbu maqolada suvda eruvchan tabiiy va sintetik polimer strukturantlarining tuproq dispersion tizimlari bilan oʻzaro taʼsirining kolloid-kimyoviy qonuniyatlari tadqiq etilgan. Polimer makromolekulalarining tuproqning alyumosilikat minerallari (montmorillonit, kaolinit, illit) sirtiga adsorbsiyalanish mexanizmlari, xususan, vodorod bogʻlanishlari, elektrostatik kuchlar va hidrofob oʻzaro taʼsirlar tahlil qilingan. Polimer zanjirlarining konformatsion holati va ularning tuproq suspenziyalarining elektrokinetik ( -potensiali) hamda reologik xossalariga taʼsiri koʻrib chiqilgan. Tadqiqotlar shuni koʻrsatadiki, polimerlar taʼsirida tuproq agregatlarining shakllanishi koagulyatsiya va koʻprik hosil boʻlish (bridging) mexanizmlari orqali kechadi. Olingan natijalar tuproq eroziyasiga qarshi kurashish va uning strukturaviy-mexanik xossalarini maqsadli boshqarish uchun yuqori samarali polimer kompozitsiyalarini loyihalashning fundamental asosi boʻlib xizmat qiladi
