Polyphenylene vinylene (PPV) coated polystyrene (PS) beads which have moderate conductivity when doped were prepared by mixing monodisperse crosslinked PS beads, the surfaces of which had been sulfonated to render them anionic, with cationic PPV precursor polymers.

The aim of the chapter is to provide the reader with a short overview of the main fillers used for polymer processing and their application and characteristics. After a brief introduction this chapter will illustrate the main characteristics of fillers and filler reinforced polymers.

On the rheology of filled polymers
Journal of Rheology, 1990This paper develops a rheological model for flow of polymer compounds highly filled by small interacting (attractive) particles. The properties of the particle phase in the compound are described by introducing a viscoelastic ‘‘particle mode’’ with an additional kinetic equation which describes the processes of rupture and restoration of flocs of ...

It is tried to examine briefly all the aspects of filler interactions with polymer ageing, including direct chemical (catalysis of degradation, stabilising effects) and physical (screen and thermooptical effects, modification of transport properties) interactions as well as indirect ones such as stabiliser trapping, influence on the rate of mechanical ...

Particulate-filled glassy polymers
Journal of Applied Polymer Science, 1978Glass beads, NaCl crystals, or other imperfections act as stress concentrators in glassy polymers causing early crazing upon stressing. Stress–strain curves of glassy thermoplastic polymers filled with uncoupled glass beads or NaCl crystals exhibit a knee, or a slope-discontinuity point.

Abstract We review the electrical properties of polymers filled with conducting particles of various sizes and shapes. dc and ac experimental behaviors in the neighborhood of the familiar insulator to conductor transition are generally in fair agreement with the predictions of percolation theory.

The rheology of filled polymers
Journal of Applied Polymer Science, 1971AbstractThe flow properties of polymer melts containing fillers of various shapes and sizes have been examined. If there is no failure of either the filler or polymer in the solid state, then the modulus enhancement for randomly distributed filler is equal to the melt viscosity enhancement under medium shear stress conditions (104 Nm−2) in simple shear

Rheological properties of filled polymers
Macromolecular Symposia, 1996AbstractThe rheological properties of two model suspensions using a Newtonian polymeric matrix are presented and discussed in light of results presented in the literature. It is shown that particle‐particle interactions in concentrated suspensions are responsible for a gel‐type behavior at very small strain and strain hardening at a critical strain ...

Magnetic powder filled polymers
IEEE Transactions on Magnetics, 1994The composite magnetic materials with commercial polymer matrix along with different magnetic fillers have been studied, with the aim of tailoring their properties. The measured magnetic parameters of the prepared samples have been compared by those calculated using a model in which the magnetic powder particles are surrounded by the thin layer of ...

Misconceptions about filled polymers
Journal of Applied Polymer Science, 1974The idea that, with filled polymers, length fraction, area fraction, and volume fraction of filler are different appears to have gained wide acceptance. The fallacy of this, except for special directions in ordered arrangements, is demonstrated. This misunderstanding has led to widespread misinterpretation of experimental results in this field.
