Propylene / 1-pentene random copolymers : preparation, characterisation and commercialisation
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: Most polypropylene copolymers commercially available have ethylene, and to a lesser degree t-butene as comonomers. Commercially available higher a-olefins, mostly even-numbered, are seldom used for the ...
Directed synthesis of polymer mesostructures
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: The objective of this research was to produce discrete, nano-shaped polymeric structures on the same length scale as, or one to one copies of, templates, deformable templates or structure-directing h ...
Porous polymeric superstructures as in-growth scaffolds for tissue-engineered vascular prostheses
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: Please refer to fulltext for abstract.
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 ...
The effect of iodo alkyl chain transfer agents on the seeded emulsion homo- and co-polimerisation of styrene and butyl acrylate
(Stellenbosch : Stellenbosch University, 1999)
ENGLISH ABSTRACT: A free-radical polymerisation process, which has characteristics of a living polymerisation system, as it is capable of producing polymers of pre-determined molecular masses with a narrow molecular ...
Synthesis and characterization of comb-polymers with controlled structure
(Stellenbosch : University of Stellenbosch, 2006-12)
Synthesis of a series of poly (methylmethacrylate)-graft-poly (styrene) polymer was carried out via free radical polymerization of methylmethacrylate and polystyrene macromonomers. The macromonomers were synthesized via ...
