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 ...
Fun with polymers : development of interactive multimedia and practical polymer science programmes
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: Multimedia was the buzzword of the previous decade. Electronic learning is the
buzzword of this decade. Both concepts changed, and are still changing the way
educators present knowledge and information ...
Polyurethane dispersions for paper coatings
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: Aqueous polyurethane (PU) dispersions were synthesized for the use in paper coatings.
These PUs contained a polyester polyol soft segment (content of 60-70%) and a urethane
hard segment (content of ...
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 ...
The effect of monosaccharide reducing sugars on the atom transfer radical polymerization of n-butyl methacrylate and methyl methacrylate
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: The effect of various organic reducing agents, in the. form of monosaccharide reducing sugars, on the
rate of atom transfer radical polymerization (ATRP) of n-butyl methacrylate and methyl methacrylate ...
