(Stellenbosch : University of Stellenbosch, 2009-03)
In papermaking, the addition of filler can be detrimental to the properties of the resulting paper hence the use of additives that enhance paper properties are of paramount importance. Syndiotacticity rich poly(vinyl ...
The influence of processing on properties of injection-moulded and lomolded components
(Stellenbosch : University of Stellenbosch, 2006-03)
Rectangular components were produced by both standard injection moulding and by a process called Lomolding. Both moulding grade polypropylene homopolymer and glass-filled polypropylene were used. The effect of processing ...
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 ...
