Tailored glycopolymers
(Stellenbosch : Stellenbosch University, 2008-12)
The synthesis of glycopolymers with various comonomers as prepared via the RAFT process is
investigated.
The macro-RAFT agent poly(3-O-methacryloyl-1,2:5,6-di-O-isopropylidene-D-glucofuranose)
(PMAlpGlc) was prepared ...
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 ...
Nanochemistry through self-assembly : polymerisation of the organised phases of polyelectrolyte-surfactant complexes
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: The general objective of this research was to develop a new approach to direct
templating, where the organised phases of polyelectrolyte-surfactant
complexes are used as hosts for organic polymerisation ...
The supramolecular chemistry of novel synthetic biomacromolecular assemblies
(Stellenbosch : Stellenbosch University, 2004-04)
ENGLISH ABSTRACT: Over the past decade peptide bola-amphiphiles have been the subject of much attention
because of their role as potential models of functionalised membranes and as new
generation surfactants. In the quest ...
The development of analytical techniques for studying degradation in impact polypropylene copolymers
(Stellenbosch : University of Stellenbosch, 2009-03)
Unstabilised polyolefins are susceptible to degradation when exposed to molecular oxygen, heat, irradiation as well as chemical and mechanical stimuli. Oxidation leads to changes in molecular properties such as molecular ...
