Investigation of the copolymerization of butyl acrylate (BA) with vinyl neononanoate (VeoVA-9)
(Stellenbosch : Stellenbosch University, 2006-12)
ENGLISH ABSTRACT: This study has the goal of illuminating structure-properties relationships for copolymers of vinyl neononanoate (VeoVa-9) and butyl acrylate (BA). The VeoVa-9/BA copolymers were prepared using solution ...
An investigation into the mechanistic behaviour of RAFT-mediated miniemulsion polymerizations.
(Stellenbosch : University of Stellenbosch, 2005-12)
Polymerization using the reversible addition-fragmentation chain transfer (RAFT) process affords a researcher control over the molecular weight and polydispersity of the final polymer. Research is being carried out ...
An investigation into the nano-structure self assemblies of amphiphiles and their fixation by polymerization
(Stellenbosch : Stellenbosch University, 2000-04)
ENGLISH ABSTRACT: This thesis is a written record of an investigation into the self-assembly of organic monomers in amphiphilic solutions. The polymerizable surfactant sodium 10-undecenoate was used alone and with different ...
The supramolecular chemistry of novel synthetic biomacromolecular assemblies
(Stellenbosch : Stellenbosch University, 2004-04)
ENGLISH ABSTRACT: Over the past decade peptide bola-amphiphiles have been the subject of much attention because of their role as potential models of functionalised membranes and as new generation surfactants. In the quest ...
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 ...
