Organic-inorganic hybrid graft copolymers of polystyrene and polydimethylsiloxane
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT: Hybrid graft copolymers of polystyrene (PSty) and polydimethylsiloxane macromonomers (PDMS) were synthesised. PSty-g-PDMS was synthesised employing the grafting through technique via a conventionally ...
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 ...
Polymer-clay nanocomposites prepared by RAFT-supported grafting
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: In materials chemistry, surface-initiated reversible deactivation radical polymerisation (SI-RDRP) has emerged as one of the most versatile routes to synthesising inorganic/organic hybrid materials ...
Mechanistic aspects of RAFT Mediated (Co) Polymerization by in situ ¹H NMR
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: In this study the kinetic and mechanistic aspects of the Reversible Addition Fragmentation Chain Transfer (RAFT) process on the copolymerization of acrylonitrile (AN) and vinyl acetate (VAc) are investigated ...
