    <title language="eng">Influence of polyvinylpyrrolidone (PVP) on alumina sols prepared by a modified Yoldas procedure</title>
    <abstract language="eng">Al13 polycations containing alumina sols, prepared by a modified Yoldas procedure were mixed with polyvinylpyrrolidone (PVP). Although Al speciation in freshly prepared sols was not affected by PVP addition the decay rate of Al13 polycations was slightly decreased in PVP-containing sols. PVP does not show any influence on particle size and particle growth. The influence of PVP addition on viscosity and flow behavior of modified Yoldas sols depends on their solids content and NO3-/Al molar ratio.</abstract>

    <title language="eng">Rheology, UV-vis transparency and particle size of modified Yoldas sols</title>
    <abstract language="eng">Alumina sols were prepared using a modified
Yoldas procedure, thus resulting in sols with high solids
content, excellent long term stability and small particle size.
PH-value ranged between 3.7 and 0.6. Sols were characterised
using rheological, UV-vis transmission and particle
size measurements. Depending on NO3-/Al molar ratio as
well as solids content, sols vary. Analysis of reduced viscosities
indicate the formation of chainlike polymeric species
above a critical solids fraction.</abstract>
