摘要：

The difference between the synthesized hydrophilic and hydrophobic polyamines for the Na+-MMT interacalation was analyzed. The hydrophobic POP-AMO affected the layered silicate intercalation to a wide 50 Å basal spacing. With the formation of low quaternary salt/amine ratio, the polyamine salt with multiple POP segments in the structure may exfoliate the layered silicates into individual platelets. The results show that the POP-segmented quaternary salts undergo an ionic exchange reaction and stretch out the layered silicates into the exfoliation.
