Abstract
The aim of this work was synthesis of grafted copolymers of poly(methacrylic acid) and starch (PMAA-graft-starch) with high percentage of grafting, G (%). The effect of temperature (55-75 degrees C), concentration of methacrylic acid monomer (0.775-1.452 mol/dm(3)), amount of initiator potassium persulfate (PPS) (0.00075-0.0025 mol), reaction time (30-270 min) and nature and amount (0.001-0.005 mol) of amine activator on percentage of grafting were investigated. The following amine activators were used: N,N-dimethylaminoethanol. N,N-diethylaminoethanol, triethylamine, propylamine, iso-butylamine, pentylamine, hexylamine, 4-(2-hidroxyethyl) morpholine and 1-(2-hidroxyethyl) piperazine. The graft copolymer was characterized by Fourier Transform Infrared Spectroscopy and Scanning Electron Microscopy. The highest G was 40.92%. Reaction conditions were as follows: 10.00 g of starch, monomer concentration was 0.775 mol/dm(3), temperature of 70 degrees C, the amount of PPS was 0.001 mol. The ...4-(2-hidroxyethyl) morpholine was used as amine activator in amount of 0.001 mol. (C) 2012 Elsevier Ltd. All rights reserved.
