Journal of Applied Polymer Science, 1994
AbstractThe ductility of a calcium carbonate‐filled amorphous copolyester PETG in a uniaxial tensite test was examined as a fiction other filler volume fraction. A ductile‐to‐quasibrittle transition occurred as the volume fraction of filler increased. This transition was from propragation of a stable neck through the entire gauge length of the specimen

Polymer Bulletin, 1990
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.

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.

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 ...

Physica A: Statistical Mechanics and its Applications, 1989
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.

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 ...

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

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 ...
