The preparation and characterization of multinuclear catalysts based on novel dendrimers : application in the oligomerization and polymerization of unsaturated hydrocarbons
(Stellenbosch : University of Stellenbosch, 2011-03)
In this thesis we describe the application of novel salicylaldimine and iminopyridyl
nickel metallodendrimer complexes as catalysts in the transformation of á-olefins as well as
in the polymerization of norbornene.

Synthesis and characterization of multiphase copolymers
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: Multiphase copolymers generally consist of copolymers where the disparate natures of each
of the segments results in complex phase-segregated morphologies in the solid state. The
outstanding properties ...
Oxazoline directed lithiation of Calix[4]arene and Ferrocene
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: The use of chiral oxazoline directed lithiation provides a highly diastereoselective (up to >99%
de) route to meta functionalised inherently chiral calixarenes. This methodology can be used on
both the ...
Analysis of vegetable oils, seeds and beans by TGA and NMR spectroscopy
(Stellenbosch : University of Stellenbosch, 2011-03)
ENGLISH ABSTRACT: Due to the commercial, nutritional and health value of vegetable oils, seeds and beans, the
analysis of their components is of much interest. In this dissertation oil-containing food
products, specifically ...
Comprehensive multidimensional gas chromatography for the analysis of Fischer-Tropsch products
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: The analysis of Fischer–Tropsch–derived (FT–derived) synthetic crude and derived products
is very challenging because of the highly complex nature of these products. In this study, the
use of comprehensive ...
