N. Scherbakoff et H. Ishida, STUDY OF THE ROLE OF SILANE-TREATED FILLER ON THE COMPATIBILITY OF POLYPROPYLENE POLYSTYRENE BLENDS AT DIFFERENT RATIOS/, The Journal of adhesion, 64(1-4), 1997, pp. 203-228
A systematic study of the effect of the filler on the immiscible blend
properties is presented as a function of the blend composition. As a
representative of semicrystalline polymer/amorphous polymer blends, a
polypropylene/polystyrene system was chosen. The presence of filler in
the blends has induced significant changes in the rheological propert
ies. This behavior is a function not only of filler surface treatment
but also of blend composition. Solid state dynamic mechanical analysis
is performed and the relaxation behavior is correlated with the morph
ology of the blends. The increase in tensile strength of the blends fi
lled with surface-treated glass beads is related to the enhancement of
the adhesion and polymer/polymer interactions.
