Microheterogeneous solid polymer electrolyte (SPE) membranes for electrocatalysis
(Stellenbosch : Stellenbosch University, 2002-04)
ENGLISH ABSTRACT: The deposition of platinum catalyst on cation-exchange membranes was achieved by
a counter diffusion deposition method known as the Takenaka- Torikai method. The
morphology of the platinum catalyst on ...
Supported zeolite A membranes. Feasibility of the static transverse synthesis : a new approach
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: As there is inadequate control of the hydrothermal synthesis technique used to date in the
synthesis of zeolite A membranes, the feasibility of a new synthesis approach was investigated,
namely the ...
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 ...
Synthesis, characterization and testing of nano-structured particles for effective impact modification of glassy amorphous polymers
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: The synthesis of structured nanoparticles, in particular core/shells, IS of great
technological and economical importance to modem materials science. One of the
advantages of structured particles is ...
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 ...
Fischer-Tropsch ionomeric waxes
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: This dissertation describes work done on Fischer- Tropsch ionomeric waxes. The
waxes are characterized with respect to the method of manufacture, the mechanism of
the oxidation process, the saponification, ...
Reversible addition-fragmentation transfer polymerization in heterogeneous aqueous media
(Stellenbosch : Stellenbosch University, 2004-04)
ENGLISH ABSTRACT: The study presented in this dissertation had as primary aim to develop pathways to
heterogeneous aqueous polymerizations that had living characteristics. To this end,
the reversible addition fragmentation ...
Groundwater chemistry and supplementary sources of freshwater in Arid environments : groundwater salinisation, solar desalination & fog collection
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: Freshwater is the most fundamental of all life-supporting resources that determine our
social, economic and political wellbeing. It is, however, only a small percentage of
the world's water resources ...
Innovative spectroscopic and chromatographic techniques for the analysis of complex polyolefins prepared by metallocene catalysis
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: The study focused on the analysis of a variety o f synthesised tailored copolymers.
During the investigation o f the samples new and innovative analytical techniques
were developed to be able to identify ...
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 ...
