Novel siloxane block copolymers
(Stellenbosch : Stellenbosch University, 2008-12)
The research presented in this dissertation was concerned with the living radical
polymerization (LRP) of an amphiphilic, water-soluble, bi-substituted and
biologically compatible acrylamide derivative, namely ...
Chemical modification of polysaccharides with hydrophilic polymers for CaCO3 crystal growth modification and filler retention, for paper applications
(Stellenbosch : Stellenbosch University, 2008-12)
Polysaccharides were modified with selected polymers via the grafting technique. Both
anionic and cationic polysaccharides were prepared. Random and crosslinked graft
copolymers were also prepared. The percentage grafting ...
