In this study, vinyl acetate, N-hydroxymethyl acrylamide (NMA), and organic montmorillonite intercalated by a dioctadecyl dimethyl ammonium bromide surfactant (MMT-DOAB) were used to prepare exfoliated nanocomposites through in situ polymerization. Wide-angle X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, power-law function equation, Newtonian fluid flow equation, Cross–Williamson model viscous equation, Hooke's law, and Poisson's ratio equation revealed the structures, dispersion, rheology, and static tensile properties. The exfoliated nanocomposites were pseudoplastic non-Newtonian fluids with good dispersion in water, great storage stability, and high static tensile strength at 6.89–8.15 MPa. The contents of NMA and MMT-DOAB increased with the changes in synthesis precursors, as the calculated molecular weights did.
