13 Claims

1. A copolymer obtained from a free-radical copolymerization of polymerizable monomers consisting of

a) 25.0 to 80.0 mol % of at least one cationic monomer is diallyldimethylammonium chloride, and

b) 1.0 to 4.4 mol % of at least one polyethylene glycol macromonomer,

c) 15.6 to 74.0 mol % of at least one uncharged acrylamide monomer, and

d) optionally, up to 30.0 mol % of at least one monomer other than monomers of components a), b) and c),

wherein each of the at least one polyethylene glycol macromonomer of component b) is a monomer of the formula:

H₂C═CR^x—O(CH₂)₄—O—(CH₃H₆O)_l—(CH₂CH₂O)_p—H

in which

R^Xis H or methyl,

on molar average is a number from 0 to 7, and

p on molar average is a number from 2 to 150.
