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 ...
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 ...
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 ...
Kinetic and mechanistic features of nitroxide mediated (co)polymerization
(Stellenbosch : University of Stellenbosch, 2011-03)

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 ...
Adamantane copolymers
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: This study concerns the incorporation of adamantane containing monomers
3-(1-adamantyl)-1-propene and 1-(1-adamantyl)-4-vinylbenzene into ethene,
propene and higher a-olefins using different catalytic ...
Porous polymeric superstructures as in-growth scaffolds for tissue-engineered vascular prostheses
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT:

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 ...
Novel α-olefin polymer systems
(Stellenbosch : Stellenbosch University, 2005-03)
ENGLISH ABSTRACT:

Synthesis, polymerisation and characterisation of a novel olefin-modified acrylate monomer, 1-methyl-1-propyl-hexel acrylate
(Stellenbosch : Stellenbosch University, 2005-03)
ENGLISH ABSTRACT: Finding use for byproducts from the chemical industry holds many advantages for a
country's economy. Synthesis of new monomers from such byproducts adds value
to otherwise otherwise low-value material.
