NMR studies on the mechanism of iodine mediated polymerisation
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: In reverse iodine transfer polymerisation (RITP), chain transfer agents (CTAs) are
generated in situ from the reaction between 2,2’-azobis(isobutyronitrile) (AIBN) and
molecular iodine. This stage of ...
Two-dimensional chromatographic characterisation of PS-b-PEO copolymers at the critical conditions of their corresponding homopolymers
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: Block copolymers are very interesting materials but they are quite complex. During polymer
synthesis only a certain amount of control can be enforced. As copolymers are made up of two
or more different ...
Novel electrospun fibres of amphiphilic organic-inorganic graft copolymers of poly(acrylonitrile)-graftpoly( dimethylsiloxane) for silicone composite reinforcement
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: Novel silicone nanocomposites were prepared using poly(acrylonitrile) (PAN) based reinforcing
fibres as well as multi-walled carbon nanotubes (MWCNTs). Compatibility of the fibre fillers with
the silicone ...
