摘要: Abstract The influence of commercially available dispersants on the rheological behaviour an unsaturated polyester–alumina composite was systematically investigated. In addition, effect a chemical surface hydrophobisation using silanisation agent determined. few cases, significant change flow properties could be observed, selection suitable dispersants, which reduce composite's viscosity will presented. Furthermore alumina content, filler's polarity and dispersion method investigated compared with empirical models for estimation critical filler load.
