Synthesis and characterization of two novel urethane macromonomers and their methacrylic/urethane graft copolymers
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT:
Polymethacrylates are well known adhesives and can carry specific functionality, but have
the disadvantage that their flexible backbones impart limited thermal stability and mechanical
strength. ...
Polypropylene/filler nanocomposites by melt compounding and in situ polymerization
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: The properties of polymer nanocomposites depend greatly on the
chemistry of the polymer matrices, the nature of the nanofillers, and the way in
which they are prepared. Understanding the synthesis–str ...
Click chemistry for the preparation of advanced macromolecular architectures
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT:
Different click chemistry methods have been used together with Reversible Addition-
Fragmentation chain Transfer (RAFT) mediated polymerization to synthesize macromolecular
architectures.
A new leaving ...
Synthesis and characterization of glycopolymer brushes
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Please refer to full text for abstract
Superparamagnetic nanoparticles for synthesis and purification of polymers prepared via controlled/"living" radical polymerization (CLRP)
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT:
Living chains prepared by RAFT polymerization and NMP reactions using Z-carboxylate and Z-phosphate RAFT agents, and X-phosphate NMP initiators, were efficiently attached to the surface of magnetic ...
Synthesis and morphological characterization of segmented and branched polydimethylsiloxane-polyester copolymers
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT:
Polydimethylsiloxane–polyester (PDMS-PES) copolymers produce materials which have
enhanced properties and take advantage of the unique properties of the two very dissimilar
components. The dissimilar ...
Localisation and quantification of chemical functional groups on pulp fibres
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: The distribution of different free chemical functional groups on wood and pulp
fibres was determined by means of atomic force microscopy (AFM) with
chemically modified tips. Because these functional ...
The effect of wood composition and compatibilisers on polyethylene/wood fibre composites
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: The effects of the macromolecular composition and content of different wood species
on the properties of wood-polymer composites (WPCs) achieved when using
poly(vinyl alcohol-co-ethylene) (EVOH) as a ...
