ABSTRACT Apparatus and method of preparing a partially hydrolyzed polymer solution; especially a partially hydrolyzed polyacrylamide solution, for use in secondary and tertiary oil recovery operations which involves the in-line introduction of a relatively concentrated solution of a hydrolyzing agent into a polymer stream having a relatively high concentration of the polymer, and thereafter intimately mixing, under heat, the polymer stream and the hydrolyzing agent while controlling the flow rate of the reaction mixture.The reaction mixture is then held in a post hydrolysis tank where the reaction is allowed to go to completion.
