Effect of Na + -Montmorillonite Modified with N,N-Diallylaminoisohexanoic Acid on the Structure and Properties of Polyamide 6

Composites of polyamide 6 and modified montmorillonite were obtained by mixing the melt in a twin-screw extruder from Jiangsu Xinda Science and Technology. The structure of the resultant composites was studied by x-ray structural analysis and scanning electron microscopy. In comparison with unfilled polyamide, the elasticity modulus, toughness, and flow index of the composites were all found to be enhanced.
