Summary:A process for producing an aqueous polymer solution, including: (a) providing a hydrated polymer that has been prepared by aqueous solution polymerisation of ethylenically unsaturated monomers, which hydrated polymer contains at least 10% by weight active polymer; (b) cutting the hydrated polymer by subjecting the hydrated polymer to at least one cutting stage containing at least one stream of aqueous liquid at a pressure of at least 150 bar to reduce the size of the hydrated polymer; and (c) dissolving the hydrated polymer in an aqueous liquid so as to obtain an aqueous polymer solution. An apparatus for producing an aqueous polymer solution.
