ABSTRACT:
Disclosed herein is a flocculating agent comprising a specified cationic polymer having an amidine structure. The cationic polymer flocculating agents according to the present invention have 20 to 90% by mole of a repeating amidine unit represented by the formula (1) and/or (2): ##STR1## The agents have a reduced viscosity of 0.1 to 10 dl/g as measured in a 1N saline solution of 0.1 g/dl at 25.degree. C.
The agents have a remarkably excellent performance as flocculating agents, in particular for organic sludge.
