英文摘要: The variation of specific surface area and chemical reactivity of nano-KH particles treated at different temperatures has been studied, The BET surface area of nano-KH decreases with the increase of heat treatment temperature, while the chemical reactivity per unit surface increases steadily. These results indicate that the state of KH surface is changed after heat treatment. Large specific surface area of nano-KH is a major factor for its high chemical reactivity, nevertheless, the surface in an activated state with high surface energy is also an important factor for its high chemical reactivity. Nano-KH alone can polymerize styrene rapidly with the formation of polystyrene.
