Effects of Fillers on Relaxation Behavior and Other Transitions

Effects of Fillers on Relaxation Behavior and Other Transitions 

A number of studies of high-surface-area fillers (surface area 100 m /g) reveal detectable increases in Tg or other changes in relaxation behavior. 

The earlier observations by Landel (1958) have also been confirmed for several systems containing very large filler particles (up to 40/zm in diameter). Thus increases in Tg as measured by dilatometry and mechanical studies have been reported by Lipatov et al (1963, 1974) for polymers such
