The interactions between titanium oxide (TiO2) and polystyrene (PS) du
ring the pan-milling process were studied. The results show that TiO2
contributes to the crushing of PS when they are ground together. Compa
red with material prepared by the traditional method, the PS/TiO2 prep
ared by pan-milling exhibits much better properties, such as impact st
rength, rheological behaviour and thermostability. It is a new method
for preparing polymer material with high performance.
