Abstract:

Starch-graft-polyacrylamide (St-g-PAM) was prepared using a salt media polymerization technique, and characterized by FITR. The type of starch and the synthesis method of different system were studied through the mass of product, the percentage of grafting (PG) and the monomer conversion (MC), and the difference polymerization system. The results showed that the pretreated starch and the salt solution system, respectively, were more advantageous than the raw starch and the aqueous solution system. The intrinsic viscosity, transmittance, product loss, penetration and apparent viscosity of St-g-PAM by salt solution polymerization were 12.49 dL•g-1, 18.6%, 0.56%, 53.96, 18.40 Pa•S, respectively. The method could get bigger branched-chain molecular than the others with high yield, high monomer conversion, high the percentage of grafting, low product losses and easy post-processing
