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 ...
Innovative spectroscopic and chromatographic techniques for the analysis of complex polyolefins prepared by metallocene catalysis
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: The study focused on the analysis of a variety o f synthesised tailored copolymers.
During the investigation o f the samples new and innovative analytical techniques
were developed to be able to identify ...
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 ...
Novel analytical approaches for studying degradation in polypropylene and propylene-1-pentene copolymers
(Stellenbosch : University of Stellenbosch, 2006-03)
Commercial polyolefins degrade under the influence of light, heat, chemical and mechanical factors. They are therefore stabilised to ensure that they maintain performance characteristics during their service life. Degradation ...
New monomer for hydrophobic acrylic copolymers and their novel properties
(Stellenbosch : University of Stellenbosch, 2006-12)
The synthesis and characterization of a new tertiary alcohol (2-octyl-2-dodecanol) and “bushy-tailed”, hydrophobic acrylic monomer (2-octyl-dodecyl acrylate) from a 1-decene dimer (2-octyl-1-dodecene) precursor that was ...
Structure/property relationships of commercial propylene/1-pentene random copolymers
(Stellenbosch : University of Stellenbosch, 2006-03)
Propylene/1-pentene random copolymers are a relatively new family of random copolymers being prepared by Sasol Polymers and reveals high impact strength, good tensile properties, excellent optical properties, good rheological ...
The structure-property relationships of polyolefins
(Stellenbosch : University of Stellenbosch, 2009-03)
Polypropylene is an extremely versatile material and has a broad spectrum of
applications due to the variations in properties which are possible with this material. The
variations in the properties of the material are ...
