PRODUCTION OF A POLYACRYLAMIDE SOLUTION USED IN AN OIL RECOVERY PROCESS ABSTRACT A process for producing an aqueous partially hydrolyzed polyacryl- amide solution employed to recover oil from a subterranean oil-bearing formation. The properties of viscosity and screen factor for an aqueous polymer solution are correlated to the polymerization reaction param- eters. Values of the parameters are selected which correlate to the specific predetermined polymer properties capable of meeting the per- formance demands of the formation and the aqueous partially hydrolyzed polyacrylamide solution is produced at the selected values of the reac- tion parameters.
