  • Introduction To Polymer Analysis | Polymers | Nitrogen

    2016-12-17 · High polymers are usually made by joining together into long chains several molecules with the same type of reactive points or groupings in their structure. These individual molecules are usually olens or other compounds with double bonds, and are called monomers. The polymer molecule often contains hundreds of monomer units.

  • Stability of Partially Hydrolyzed Polyacrylamides at ...

    2009-6-29 · However, Maitin demonstrated that if the mobility of the injected polymer formulation was low enough, the fresh water polymer bank could maintain its integrity during displacement of oil in a reservoir with saline brine. In concept, this idea could be extended to application of HPAM solutions in hot reservoirs with saline, high-hardness brines.

    2015-10-4 · Polyacrylamides constitute a class of polymers that can entirely dissolve or swell in water to form a solution or hydrogel, respectively. Free radical polymerization of acrylamide monomer, using both solution and inverse emulsion polymerization, was applied to produce polyacrylamide with various molecular weights. This investigation was focused on the production …
