The effect of controlled degradation with an organic peroxide on the molecular characteristics and properties of heterophasic propylene-ethylene copolymers (HECO)
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: Heterophasic copolymers (also known as HECO polymers) or often referred to only as impact
copolymers or block copolymers comprise a polymer matrix with a dispersed rubbery
copolymer phase. The polymer ...
Highly filled water based polymer/clay hybrid latexes
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: The use of co-sonication (ad-miniemulsion) polymerisation for the preparation of highly filled polymer/clay hybrid latexes is described. Laponite (Lap) content levels in the range of 10–50 wt% were ...
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. ...
Kinetic and mechanistic features of nitroxide mediated (co)polymerization

Ethylene and propylene copolymers utilizing Fishcer-Tropsch 1-olefins
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: From the Sasol Fischer- Tropsch process, a variety of different a-olefins are produced.
Sasol recently started presenting these a-olefins to polymer producers. To
demonstrate the application possibilities ...
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 ...
Self-assembling metal coatings from phosphated and silicone-modified polyurethane dispersions
(Stellenbosch : Stellenbosch University, 2001-03)
ENGLISH ABSTRACT: Self-emulsifiable and self-assembling nano-particle phosphated and siloxane-modified
polyurethane dispersions, for use in metal coatings, were synthesised from a new
phosphate monomer, a carboxylate ...
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.
Multidimensional separation of complex polymers according to microstructure
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Complex polymer systems have multiple distributions with regard to molecular parameters
such as molar mass, functionality, chemical composition, molecular architecture and
microstructure. These distributions ...
