Abstract
The elastic modulus of polystyrene/polyepichlorohydrin, PS/PECH, blend s was studied in the whole composition range. It was found that elasti c modulus varied with the volume fraction of PS in the blends and got a divergence at a critical volume fraction of PS. Percolation concept was applied to treat the experimental results. Percolation threshold d efined as critical volume fraction of PS was found to be about 0.40 an d percolation exponent was about 2.0+/-0.1, which was approximately in agreement with de Gennes' scalar elastic percolation theory and Wu's experimental results.
