Synthesis and characterization of glycopolymer brushes
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Please refer to full text for abstract
Electrospun antimicrobial and antibiofouling nanofibres
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: The main objective of this study was to develop electrospun nanofibres with both antimicrobial and antibiofouling properties for possible application in water filtration. To do this, two routes were ...
Preparation of polymer-clay nanocomposites via dispersion polymerization using tailor-made polymeric surface modifiers
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: Fully exfoliated polystyrene-clay nanocomposites were prepared via free radical polymerization in dispersion polymerization, in a mixture of ethanol and water. Sodium montomorillonite clay (MMT) was ...
N-vinylpyrrolidone-vinyl acetate block copolymers as drug delivery vehicles
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: The primary aim of this study was to investigate the feasibility of the amphiphilic block
copolymer poly((vinylpyrrolidone)-b-poly(vinyl acetate)) (PVP-b-PVAc) as a vehicle for
hydrophobic anti-cancer ...
The use of chromium/bis(diphenylphosphino)amine catalysts in tandem ethylene copolymerization processes
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: The possibility of utilizing the chromium/bis(diphenylphosphino)amine (PNP) type of
catalysts in ethylene polymerization processes was investigated. These processes
include the production of linear low ...
Superparamagnetic nanoparticles for synthesis and purification of polymers prepared via controlled/"living" radical polymerization (CLRP)
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT:
Living chains prepared by RAFT polymerization and NMP reactions using Z-carboxylate and Z-phosphate RAFT agents, and X-phosphate NMP initiators, were efficiently attached to the surface of magnetic ...
Synthesis and morphological characterization of segmented and branched polydimethylsiloxane-polyester copolymers
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT:
Polydimethylsiloxane–polyester (PDMS-PES) copolymers produce materials which have
enhanced properties and take advantage of the unique properties of the two very dissimilar
components. The dissimilar ...

Molecular weight effects on crystallization of polypropylene
(Stellenbosch : University of Stellenbosch, 2011-03)
ENGLISH ABSTRACT: The crystallization of polyolefins is an important parameter in determining the properties of
such materials. The crystallization phenomenon generally depends on the molecular
symmetry (tacticity) and ...
New approaches to the synthesis and exfoliation of polymer/functional graphene nanocomposites by miniemulsion polymerization
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: New methods are described for the synthesis of polymer/graphite nanocomposites using the
miniemulsion polymerization process. Natural graphite was functionalized by oxidation to
produce graphite oxide ...
