Reversible addition fragmentation chain transfer (RAFT) mediated polymerization of N-vinylpyrrolidone
(Stellenbosch : University of Stellenbosch, 2008-03)
Xanthate-mediated polymerization was investigated as a tool for the preparation of well-defined poly(N-vinylpyrrolidone) and copolymers of N-vinylpyrrolidone. Some results regarding the monomer vinyl acetate are included, ...
Mechanistic studies of reversible addition-fragmentation chain transfer mediated polymerization
(Stellenbosch : Stellenbosch University, 2004-03)
ENGLISH ABSTRACT: To comply with the ever growing demands for materials with better properties and complex architectures, polymer chemistry has resorted to the use of living free radical polymerization techniques. Despite ...
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 ...
