Compatibility of polyvinyl alcohol and poly(methyl vinyl ether-co-maleic acid) blends estimated by molecular dynamics

Author: Moolman, FS ; Meunier, M ; Labuschagne, Philip W ; Truter, PA Date: 25 Jul 2005 The CSIR has developed a novel oxygen barrier technology for plastics packaging based on interpolymer complex formation between PVOH (polyvinyl alcohol) and PMVE-MA (poly(methyl vinyl ether-co-maleic acid)). As interpolymer complexation ... Read more
Electro-osmotic pumping of sodium chloride solutions

Author: Schoeman, JJ ; van Staden, JF Date: 20 Aug 1997 Electro-osmotic pumping (EOP) theory and its characteristics (transport numbers, brine concentration, current density, current efficiency, electro-osmotic coefficients, etc.) of Selemion AMV and CMV ion-exchange membranes were studied. The ... Read more
Expert system for the optimisation of melt extruded net structures

Author: Rawal, A ; Davies, PJ Date: 2005 Net structures were produced by replacing the static die (spinneret) with two concentric dies (consisting of slots) rotating in opposite directions in a melt extrusion process. A series of net structures and filaments were produced from a ... Read more
Rheology of organoclay suspension

Author: Hato, MJ ; Zhang, K ; Ray, SS ; Choi, HJ Date: May 2011 The authors have studied the rheological properties of clay suspensions in silicone oil, where clay surfaces were modified with three different types of surfactants. Dynamic oscillation measurements showed a plateau-like behavior for all the ... Read more
Rotational effects of polymeric fluids on shape of filaments in melt extruded net structures

Author: Rawal, A ; Gonsalves, JW Date: 2006 The present work deals with the net structures, which are produced by replacing the static die (spinneret) with two concentric dies rotating in opposite directions in a melt extrusion process. These dies consist of defined number of slots ... Read more
