Study the effect of alkyl substitution of monomers on properties of polyesters
(North-West University, 2015)This study concerned the synthesis of modified terephthalic acid monomers and branched dialcohols for the synthesis of polyesters with different properties. Monomers were prepared by esterification of terephthalic acid ... -
Synthesis and characterisation of high performance flocculants and superabsorbents from chemically modified starch and glycerol
(North-West University (South Africa), Potchefstroom Campus, 2015)Superabsorbent polymers from chemically modified starch and glycerol have been prepared by acryloylation of starch followed by grafting with acrylic acid (AA) using Fenton’s initiation system (Fe2+/ H2O2). Fourier-transform ...
