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 ...
