ABSTRACT Water Soluble Polymers A suspension may be flocculated using a water soluble substantially linear polymer having a single point intrinsic viscosity above 3 and that is a copolymer of two or more ethylenically unsaturated monomers including at least 0.5% by weight of monomer carrying pendant hydrophobic groups. The cationic polymers are novel. Preferred polymers are those in which the hydrophobic group is introduced as an allyl ether.
