Preparation and characterization of a New polymers for retention water as a Chemical method for decreasing irrigation waters

Abstract

Using hydrophilic monomers, four new polymers for water retention has been prepared as Super Absorption Polymers (SAP) of water, under nitrogen atmosphere, in a free radical polymerization route, using Ammonium per-sulfate (APS) as an initiator and at constant temperature 70C0 and on several types ( Composite, Copolymer, Grafting and Modified ). H1NMR, FT-IR Spectroscopy were using for products characterization, and Differential Scanning Calorimetry) DSC) for thermals stability study. Water absorption capacity for hydrogel was n448 to 3163wt / wt).
