Hydrophobic core/shell particles via miniemulsion polymerization
(Stellenbosch : University of Stellenbosch, 2006-12)
Hydrophobic core/shell latex particles were synthesized for use in barrier coatings using the
miniemulsion polymerization process. Particles with liquid or with hard cores were
successfully synthesized using miniemulsion ...
Novel α-olefin polymer systems
(Stellenbosch : Stellenbosch University, 2005-03)
ENGLISH ABSTRACT:

Synthesis, polymerisation and characterisation of a novel olefin-modified acrylate monomer, 1-methyl-1-propyl-hexel acrylate
(Stellenbosch : Stellenbosch University, 2005-03)
ENGLISH ABSTRACT: Finding use for byproducts from the chemical industry holds many advantages for a
country's economy. Synthesis of new monomers from such byproducts adds value
to otherwise otherwise low-value material.
The ...
The synthesis of 1-butene oligomers with vinyl endgroups and their use in further reactions
(Stellenbosch : University of Stellenbosch, 2007-03)
This study comprises the synthesis, functionalization, and characterization of 1-butene
oligomers, as well as the synthesis of oligobutene-based macro-RAFT agent.
The directed oligomerization of 1-butene was carried out ...
New monomer for hydrophobic acrylic copolymers and their novel properties
(Stellenbosch : University of Stellenbosch, 2006-12)
The synthesis and characterization of a new tertiary alcohol (2-octyl-2-dodecanol) and “bushy-tailed”, hydrophobic acrylic monomer (2-octyl-dodecyl acrylate) from a 1-decene dimer (2-octyl-1-dodecene) precursor that was ...
Self-healing coatings based on thiol-ene chemistry
(Stellenbosch : University of Stellenbosch, 2009-03)
The work presented in this dissertation describes the development of self-healing
coatings based on thiol-ene chemistry. The approach was to synthesize capsules with
thiol and ene compounds separately encapsulated. These ...
Metallocene and Ziegler-Natta catalyzed polypropylene utilizing 1-heptene
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: This study concerns the copolymerization of propylene with l-heptene. The
percentage of l-heptene used as co-monomer in the polymerization reactions was
varied from 5% to 20% in order to compare a variety ...
The structure-property relationships of polyolefins
(Stellenbosch : University of Stellenbosch, 2009-03)
Polypropylene is an extremely versatile material and has a broad spectrum of
applications due to the variations in properties which are possible with this material. The
variations in the properties of the material are ...
Novel siloxane block copolymers
(Stellenbosch : Stellenbosch University, 2008-12)
The research presented in this dissertation was concerned with the living radical
polymerization (LRP) of an amphiphilic, water-soluble, bi-substituted and
biologically compatible acrylamide derivative, namely ...
Design, synthesis and characterization of novel raft agents
(Stellenbosch : University of Stellenbosch, 2005-12)
This thesis begins with the description of the preparation of thirteen dithioesters (of the form Z-
(C=S)-S-R) which were characterized via Fourier-transform infrared spectroscopy (FT-IR), nuclear
magnetic resonance ...
