The glass transition temperature, dynamic shear moduli and bulk viscosities of Phenoxy PKHH filled with glass beads and Attapulgite clay were investigated. The glass temperature of the polymer increased with increasing filler concentration and with increasing specific surface area of the filler. The average transition temperature was described by a simplified two-phase mixture model of a layer of immobilized polymer surrounding each filler particle and the unaffected portion of the polymer matrix.
