Abstract

Nowadays, use of polymeric mulch such as the polymer based on ACRYLAMIDEs is developing due to being eco-friendly, safety, and low cost. Polyacrylamide is odorless, colorless, non-polluting the ground water and surface water, soil and plant tissues. In this study, for the first time, COPOLYMER based on ACRYLAMIDE and ACRYLIC ACID was used in small-scale plots in experimental conditions for use in soil for the purpose of its stabilization and preventing its loss.COPOLYMER based on ACRYLAMIDE and ACRYLIC ACID was synthesized by free radical polymerization.The water-soluble polymer synthesized by free radical polymerization and characterized using Fourier-transform infrared spectroscopy and thermogravimetric analysis. To calculate the negative charge density of samples, titration method was performed. By increasing density of negative charge of polymer chains, the apparent viscosity decreases with higher rate. It can be concluded that in the presence of ACRYLIC ACID, the ions shrank and became more like spheres which ultimately results in coil-like configuration. As the COPOLYMERization reaction proceeds from 50% to 90% weight percent of ACRYLIC ACID, the rate slows down due to accumulation of negative charges and the molecular weight of COPOLYMERs decreases with increasing the anionic degrees of COPOLYMERs.Finally, SOIL LOSS was determined using 0.4, 0.6, 1, 2, 3, 4 and 6 gr/m2 of COPOLYMERs in water and solutions sprayed on the soil surface before implementation of artificial rainfall, also its continuity in 30min rainfall was studied.
