Propylene / 1-pentene random copolymers : preparation, characterisation and commercialisation
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: Most polypropylene copolymers commercially available have ethylene, and to a
lesser degree t-butene as comonomers. Commercially available higher a-olefins,
mostly even-numbered, are seldom used for the ...
Structure/property relationship of model alkali-soluble rheology modifiers synthesised via the RAFT process
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: Alkali-soluble rheology modifiers are commercially synthesised via conventional freeradical
polymerisation processes. This results in the end product having certain
limitations; there is poor control ...
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 ...
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 ...
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 ...
Porous polymeric superstructures as in-growth scaffolds for tissue-engineered vascular prostheses
(Stellenbosch : Stellenbosch University, 2001-12)
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 ...
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 ...
