The effect of in-process ethylene incorporation on the evolution of particle morphology and molecular characteristics of commercial heterophasic ethylene propylene copolymers (HEPCs)
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Impact copolymers or heterophasic polypropylene-ethylene-co-propylene copolymers (HEPCs) commonly produced in industry are valued for their good mechanical properties, combining the rigidity of the ...
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 ...
The development of analytical techniques for studying degradation in impact polypropylene copolymers
(Stellenbosch : University of Stellenbosch, 2009-03)
Unstabilised polyolefins are susceptible to degradation when exposed to molecular oxygen, heat, irradiation as well as chemical and mechanical stimuli. Oxidation leads to changes in molecular properties such as molecular ...
