A new hectorite/poly(AM/IA) nanocomposite hydrogel was synthesized by inverse microemulsion polymerization. Influences of hectorite content on water absorbency and salt solution absorbency, swellability, pH-sensitivity, gel strength and temperature-resistance of the nanocomposite hydrogel were investigated. Water and salt solution absorbencies, pH-sensitivity and swellability decreased while gel strength...
A series of hydrophobically associating copolymers of acrylamide and hydrophobic stearyl methacrylate as comonomers were prepared by microemulsion polymerization. The rheological properties of the copolymers in aqueous solution depended on the content of hydrophobic monomer, initiator amount, surfactant concentration, the copolymer concentration and the addition of salt. The hydrophobically associating...
