Cross-link variation in polyacrylic acid polymers for coating fertilizer pellets, promoting controlled release
(North-West University (South Africa), 2020)Polyacrylic acid (PAA) cross-linkers have been prepared by the esterification of acrylic acid (AA) with linear diols and glycerol using an acid exchange resin catalyst (Amberlyst B-23) and Dean-Stark water removal to promote ... -
The development of non-heme N4-tetradentate Manganese(II) complexes for alcohol oxidation
(North-West University (South Africa), 2019)A series of known and novel non-heme N₄-tetradentate ligands, R,R- and S,S-L5 - L12, of the BPMCN type (BPMCN = N,N'-dimethyl-N,N'-bis(2-pyridylmethyl)-(R,R/S,S)-1,2-diaminocyclo-hexane) containing different N-donors ... -
Sintese van amino-arielaldehied verbindings
(North-West University, 2015)Die soeke na sterk hoë-verrigtingspolimere het gelei tot die idee om ʼn volledig gekonjugeerde polimeer te ontwikkel vir moontlike gebruik in die motorindustrie. Hierdie polimeer moet soortgelyke eienskappe as dié van ... -
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 ...
