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 ...
Novel multidimensional fractionation techniques for the compositional analysis of impact polypropylene copolymers
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: Impact Polypropylene Copolymers (IPCs) are extremely complex materials, consisting of a mixture of
polypropylene homopolymer and copolymers having different comonomer (ethylene) contents and
chemical ...
The preparation of polyolefin nanofibres by solution electrospinning
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: Solution electrospinning is a technique used to produce polymer micro- or nanofibres. Recently a great deal of research has been done on the application of polymer nanofibres produced by this method.
The ...
The effect of molecular composition on the properties of polyolefin-wood composites
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: Polymer composites, and in particular wood-polymer composites have become commercially and
environmentally important materials. Studies in polyolefin-wood composites have mostly focused
on polypropylene ...
Alternating hetero-arm copolymer molecular brushes as scaffolds for inorganic nano-wires
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: This study describes the synthesis and self-assembly of hetero-arm molecular brushes (hetero-arm MBs). These MBs consist of two polymeric side chains (SCs) of different natures, alternatingly distributed ...
Nanocolorants for hot-melt inks
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: A new class of nanocolorants is described for the use as a colorant in hot-melt ink application for ink-jet printing technology. An inverse miniemulsion polymerization process was utilized successfully ...
Multidimensional analytical techniques for the characterization of aliphatic polyesters
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: Complex polymers are defined by their distributive properties with respect to molecular weight, chemical
composition, functionality and molecular topology. As a result, polymer properties are very ...
