Abstract: | Cross-linked acrylonitrile-divinylbenzene copolymer beads have been synthesized by suspension polymerization in presence of an inert diluent (toluene). In this study a set of experiments has been performed to evaluate the physical features of the beads. The influence of the pre-polymerization step, process stirring conditions and type of polymerization initiator on the polymer particle size distribution, apparent density and visual appearance by optical microscopy was investigated. |
