Poly(acrylic acid-co-acrylamide) has large number of ionic and nonionic hydrophilic groups, such making the rheological behavior of its solution complex. In this research, four different potential crosslinking agents which contains activating hydroxyl group and unsaturated bond were introduced into the poly(acrylic acid-co-acrylamide) polymer during aqueous solution radical polymerizations. Rotary viscosimeter was chosen to characterize the apparent viscosity of poly(acrylic acid-co-acrylamide) concentrated solutions. Temperature, concentration of the aqueous concentrated solutions and proportion of potential crosslinking agent are the most important factors. Results shows that the apparent viscosity of PAAM concentrated solution decreases with the increase of temperature, the decreases of concentration of the aqueous concentrated solutions and the proportion of potential crosslinking agent.

Poly Acrylic Acid

In the reaction of dianions with poly(methyl methacrylate), only an insignificant amount of insoluble crosslinked product is obtained. If, however, the concentration of grafting dianions approaches that of ester groups, the amount of poly(methyl methacrylate) which may thus be crosslinked becomes quite significant. Dications, too, can bring about crosslinking of only an insignificant number of poly(methyl methacrylate) chains. Carboxylic groups in poly(acrylic acid) react with dianions and dications in an anhydrous medium similarly to ester groups. On the other hand, in the presence of a cocatalytic amount of water dications are more readily bound to carboxylic groups, forming a covalent bond. The relatively highest efficiency was observed in the bond formation between dication and the poly[styrene-alt-(maleic anhydride)], both in an anhydrous medium and in the presence of H2O.
