ABSTRACT:
A water soluble graft copolymer useful for dewatering wastewater having the structure: ##STR1## wherein E is the repeat unit obtained after polymerization of an .alpha., .beta. ethylenically unsaturated compound, the molar percentage of a:b is from about 95:5 to 5:95, with the proviso that the sum of a and b equals 100% G comprises the structure: ##STR2## wherein d is a cationic monomer, R.sub.1, R.sub.2 and R.sub.3 are the same or different and are hydrogen or a lower alkyl group having C.sub.1 to C.sub.3, F is the salt of an ammonium cation and the molar percentage of c:d is from 95:5 to 5:95 with the proviso that the sum of c and d equals 100%.
