Polymer A was synthesized by aqueous solution polymerization used acrylic acid and acrylamide with potassium persulfate as initiator. Organic modified bentonite sample was prepared by mixing extrusion method with polymer A as an organic modifier. The structure and morphology of the sample were examined by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The results show that the crystal spacing of the organic modified bentonite changes from 1.269 to 1.322 nm, and the organic modified bentonite still maintains the layered structure with organic groups in the layer. The organic modified bentonite was successfully prepared.
