Aqueous Two-Phase System in the Synthesis of Starch Graft Acrylamide Polymer

Abstract:

With starch as base material, acrylamide (AM) as raw material, polyethylene glycol (PEG20000) as dispersing medium, in aqueous two-phase system synthesized starch grafting acrylamide polymer. Through the indoor experiment, determine the optimum process conditions of polymerization reaction, the initial monomer concentration was 15%, PEG20000 concentration of 10%, m (ST) : m (AM) = 3:7, dosage of initiator is 0.1%, T = 50 °C, T = 6 h. Get monomer conversion was 98.5%, the characteristic viscosity.methods according to 761.5 mg/L of graft copolymerization. Of product have been characterized through infrared spectrum and analysis.
