Abstract

PURPOSE: To obtain the subject powdery improver having excellent water filterability and retention effect, obtainable a satisfactory water filtration effect with a low using amount and contrivable to steep cost reduction, comprising a cationic polymer containing a specific monomer as an essential construction unit. CONSTITUTION: This water filterability improver contains a monomer (preferably 2-acryloyloxyethyltrimethylammonium chloride) expressed by the formula (R1 -R3 are each H, a 1-4C alkyl or aralkyl; A is O or NH; Z is a 1-4C alkylene, a 2-4C hydroxyalkylene or phenylene; and X<-> is an anion formable a salt) as an essential constituting unit and preferably a cationic polymer containing other vinyl monomer (preferably acrylamide, styrene or acrylonitrile) in which a molar ratio of the monomer of the formula to the other monomer is (80/20)-(10/90).
