Flow behaviour of polyvinyl alcohol (PVOH) modified blends of polyvinyl acetate (PVAc)/natural rubber (NR) latexes
During compounding processes, polymer latexes are mixed with various colloidal systems (in particular, PVOH) or surface-active agents to modify the flow behaviour in order to suit the manufacturing process. In this study, the flow behaviour of aqueous dispersed PVAc, NR and different mixed dispersions were investigated both in the absence and presence of PVOH as flow modifier, using an Ostwald ...
متن کاملAnisotropic polyvinyl alcohol hydrogel for cardiovascular applications.
Polyvinyl alcohol (PVA) is a hydrophilic polymer with various characteristics desired for biomedical applications and can be transformed into a solid hydrogel by physical crosslinking, using a low-temperature thermal cycling process. As with most polymeric materials, the mechanical properties of the resultant PVA are isotropic, as oppose to most soft tissues, which are anisotropic. The objectiv...
متن کاملPolyvinyl alcohol particle superficial morphology.
We appreciated the research by Derdeyn et al (1) from the Mallinckrodt Institute of Radiology concerning the size and suspension characteristics of polyvinyl alcohol (PVA) particles. We do agree that both size and suspension characteristics of PVA represent relevant parameters affecting the aggregation of particles during injection. In addition to these two variables, we considered further para...
متن کاملPolyvinyl alcohol particle size and suspension characteristics.
PURPOSE To evaluate the size and shape of commercially available polyvinyl alcohol (PVA) particles and to determine whether they change in size when suspended in nonionic contrast and in a solution of nonionic contrast and absolute alcohol. METHODS The two-dimensional area and the long and short axis of PVA particles from several different vendors were measured using a light microscope attach...
متن کاملSynthesis and enhanced mechanical properties of nano Zinc Oxide in Polyvinyl alcohol and Polyvinyl pyrollidone composite film
Zinc oxide nanoparticles have been synthesized by chemical reaction method. Polyvinyl alcohol (PVA) composite film filled with nanometric, monodispersed zinc oxide nano particles prepared by PVA solution and nanozinc oxide. Polymer blend with ZnO nanoparticle composite film has prepared by casting technique. The property of nano composites depends greatly on the chemistry of polymer matrices....
