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 ...
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 ...
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 ...
Porous polymeric superstructures as in-growth scaffolds for tissue-engineered vascular prostheses
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT:
Please refer to fulltext for abstract.
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 ...
Chemical modification of polysaccharides with hydrophilic polymers for CaCO3 crystal growth modification and filler retention, for paper applications
(Stellenbosch : Stellenbosch University, 2008-12)
Polysaccharides were modified with selected polymers via the grafting technique. Both
anionic and cationic polysaccharides were prepared. Random and crosslinked graft
copolymers were also prepared. The percentage grafting ...
