METHOD FOR PREPARING DILUTE POLYMER SOLUTIONS ABSTRACT OF THE DISCLOSURE A method for preparing dilute aqueous polymer solutions, especially dilute aqueous partially hydrolyzed polyacrylamide solutions, for use in secondary and tertiary oil recovery processes. The method comprises producing a concentrated polymer solution in a polymerization reactor and diluting the resulting gel-like, relatively high concentration polymer solution to obtain a free-flowing, relatively low concentration polymer solution by means of a staged dilution process. In each stage, an aqueous diluent is combined with the polymer solution to produce a nonuniform mixture which is maintained in a vessel in a quiescent state until the mixture becomes uniform. The stages are repeated as many times as necessary until the free-flowing, relatively low concentration polymer solution is obtained.
