The invention relates to a polymer comprising a central structure to which n branches are covalently attached, wherein n is an integer from 1 to 50, wherein the branches comprise polyacrylamide moieties, wherein the theoretical number average molecular weight of the polymer is at least 100,000g/mol. This polymer is especially suitable for use in enhanced oil recovery.
