Film formation and thermal transitions of polymers studied by atomic force microscopy
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: The kinetics of drying and film formation of different polymeric latices were studied.
Various theoretical models predict a strong dependency of the film formation
characteristics on the particle size ...
Ethylene and propylene copolymers utilizing Fishcer-Tropsch 1-olefins
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: From the Sasol Fischer- Tropsch process, a variety of different a-olefins are produced.
Sasol recently started presenting these a-olefins to polymer producers. To
demonstrate the application possibilities ...
Directed synthesis of polymer mesostructures
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: The objective of this research was to produce discrete, nano-shaped polymeric structures on the
same length scale as, or one to one copies of, templates, deformable templates or structure-directing
h ...
Olfactory communicatiaon : chemical characterization of the interdigital secretion of the black wildebeest, Connochaetes gnou
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: The black wildebeest, Connochaetes gnou, is a terriorial animal and although it is not
generally accepted, it is believed that it defines its territory by scent marking, using
interdigital and preorbital ...
Separation and speciation of biodegradable complexes using capillary zone electrophersis
(Stellenbosch : Stellenbosch University, 2004-12)
ENGLISH ABSTRACT:
Separation of the metal ions Cu2+, Pb2+, Cd2+ Mn2+, Cr3+, Fe3+ and Zn2+ with poly
ethylenediamine tetra-acetic acid (EDTA), ethylenediamine disuccinic acid ([S,S']-
EDDS) and ethylenediamine dimalonic ...
Tin-bemiddeling van inositolderivatisering
(Stellenbosch : Stellenbosch University, 2000-03)
ENGLISH ABSTRACT: The aim of this thesis is to use tin-mediated reactions to differentiate between the four
zones in the myo-inositol ring that consists of five contiguous equatorial and one axial
hydroxyl groups. It ...
Adamantane copolymers
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: This study concerns the incorporation of adamantane containing monomers
3-(1-adamantyl)-1-propene and 1-(1-adamantyl)-4-vinylbenzene into ethene,
propene and higher a-olefins using different catalytic ...
Self-assembling metal coatings from phosphated and silicone-modified polyurethane dispersions
(Stellenbosch : Stellenbosch University, 2001-03)
ENGLISH ABSTRACT: Self-emulsifiable and self-assembling nano-particle phosphated and siloxane-modified
polyurethane dispersions, for use in metal coatings, were synthesised from a new
phosphate monomer, a carboxylate ...
Porous polymeric superstructures as in-growth scaffolds for tissue-engineered vascular prostheses
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT:
Please refer to fulltext for abstract.
Ontwikkeling van instrumentasie vir omvattende tweedimensionele gaschromatografie
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: Even capillary gas chromatography does not always give complete separation of the
components of complex mixtures. During the last few decades several two-dimensional
gas chromatographic techniques were ...
